Abstract
A synthetic route to the bench-stable fluorinated masked carbene reagent diethyl 2-diazo-1,1,3,3,3-pentafluoropropylphosphonate, bearing a trifluoromethyl and a difluoromethyl group is reported for the first time. Its application in CuI-catalyzed cyclopropanation reactions with aromatic and aliphatic terminal alkenes under mild reaction conditions is demonstrated. In total, sixteen new cyclopropanes were synthesized in good to very good yields.

Abstract
The syntheses of acyclic nucleoside phosphonate (ANP) analogs linked with cyclic systems
are described in the present review. The purpose of the review is to report the methodology of
ANP analogs and to give an idea on the synthesis of a therapeutic structural feature of such analogs.
The cyclopropane systems were mainly prepared by diazomethane cyclopropanation catalyzed by
Pd(OAc)2, intramolecular alkylation, Kulinkovich cyclopropanation, and use of difluorocyclopropane,
and so forth. The preparation of methylenecyclopropane system was made by diazoacetate
cyclopropanation catalyzed by Rhodium followed by addition-elimination reactions. For the preparation
of a variety of tethered 1,2,3-triazole systems, 1,3-dipolar cycloaddition between azidealkylphosphonates
and propargylated nucleobases was mainly applied. The formation of various
phosphonate moieties was achieved via phosphonylation of alkoxide, cross-coupling between
BrZnCF2P (O)(OEt)2 with iodoalkens catalyzed by CuBr, Michaelis-Arbuzov reaction with phosphite,
and Rh(II)-catalyzed O-H insertion, and so forth.

Abstract
9-(5',5'-Difluoro-5'-phosphonopentyl)-9-deazaguanine (DFPP-DG) was designed as a multi-substrate analogue inhibitor against purine nucleoside phosphorylase (PNP) on the basis of X-ray crystallographic data obtained for a binary complex of 9-(5',5'-difluoro-5'-phosphonopentyl)guanine (DFPP-G) with calf-spleen PNP. DFPP-DG and its analogous compounds were synthesized by the Sonogashira coupling reaction between a 9-deaza-9-iodoguanine derivative and omega-alkynyldifluoromethylene phosphonates as a key reaction. The experimental details focused on the synthetic chemistry along with some insights into the physical and biological properties of newly synthesized DFPP-DG derivatives are disclosed.

Abstract
9-(5',5'-difluoro-5'-phosphonopentyl)-9-deazaguanine (DFPP-DG) was designed as a multi-substrate analogue inhibitor against purine nucleoside phosphorylase (PNP) on the basis of X-ray crystallographic data obtained for a binary complex of 9-(5',5'-difluoro-5'-phosphonopentyl)guanine (DFPP-G) with calf spleen PNP. DFPP-DG and its analogous compounds were adjusted by length of the linker achieved by the Sonogashira-coupling reaction between a 9-deaza-9-iodoguanine derivative and omega-alkynyldifluoromethylene phosphonates as a key reaction. DFPP-DG is a very potent PNP inhibitor with apparent inhibition constants (in the presence of 1 mM phosphate) of 4.4 and 8.1 nM versus calf spleen and human erythrocyte PNPs, respectively. One of its analogues, homo-DFPP-DG, with longer chain linking phosphonate and 9-deazaguanine is even more potent versus human enzyme, with an apparent inhibition constant of 5.3 nM (in the presence of 1mM phosphate).

Abstract
9-(5',5'-Difluoro-5'-phosphonopentyl)guanine (DFPP-G) and its hypoxanthine analogue (DFPP-H) were modified by introducing a methyl group to all possible positions of the linker connecting a purine and difluoromethylenephosphonic acid moiety to evaluate the effects of the methyl group on inhibition against purine nucleoside phosphorylase. The methyl group on the linker affected the inhibition in a positional-dependent manner. Inhibitory potency of alpha-methyl and beta-methyl-substituted analogues of DFPP-H increased by about 600- to 1000-fold upon converting to cyclopropane nucleotide analogue (+/-)-4.

Abstract
This paper covers recent publications from our laboratory on the synthesis of a variety of phosphonate and phosphinate derivatives. New methods for the enantioselective synthesis of alpha-hydroxyphosphonates were established by Lewis acid-mediated cleavage of homochiral 1,3-dioxaneacetals with P(OEt)(3) and chiral metal ligand-mediated hydrophosphonylation of aldehydes. Two diastereomers of HPmp derivatives were prepared by an application of these methods. The HPmp derivatives were convered to FPmp derivatives but with low diastereoselectivity. Hydrophosphonylation of alpha-aminoaldehydes afforded threo- and erythro-beta-amino-alpha-hydroxyphosphonates under chelation and nonchelation controlled conditions, respectively. The asymmetric dihydroxylation of alpha, beta-, and beta, gamma-unsaturated phosphonates with AD-mix-alpha and AD-mix-beta reagents gave alpha, beta- and beta, gamma-dihydroxyphosphonates with high enantioselectivity. The method was applied to the kinetic resolution of racemic alpha-oxygetated beta, gamma-unsaturated phosphonates. Treatment of allyloxymethylphosphonates with the base afforded alpha-hydroxyphosphonates via the [2,3]-Wittig reaction. Threo- and erythro-beta-amino-alpha-hydroxyphosphinates were obtained with high diastereoselectivity by phosphinylation of alpha-aminoaldehydes in the presence of (R)- and (S)-ALB, respectively. The phosphinylation of alpha-oxygenated aldehydes afforded the corresponding alpha, beta-dioxygenated phosphinates, but with low diastereoselectivity. Sphingomyelin analogues containing CF(2)PO(OH)(2) were synthesized starting from (S)- and (R)-Garner aldehyde for the purpose of obtaining potent sphyngomyelinase inhibitors. A useful method for the synthesis of alpha, alpha-difluorobenzylphosphonates was established based on the cross coupling reaction of an iodobenzene derivative with ZnCuBr(2)CF(2)PO(OEt)(2). The synthetic utility of ZnCuBr(2)CF(2)PO(OEt)(2) was examined to obtain alpha, alpha-difluoromethylenenphosphonates. The method was applied to a synthesis of PNP-inhibitory active compounds by combination of the purine base and alcohols containing difluoromethylenephosphonate. The methodology for the beta-selective N-glycosylation of 2,3-dideoxy glucoside was established by introducing phosphonothioates at the 3-position of glycosyl doners instead of phosphonate. Synthesis of new acylic nucleotide analogues designed based on the structural modification of ARS2267 is also described. Finally, kiral synthesis of some phosphonates was achieved using lipase through kinetic resolution.

Abstract
We previously found that Grignard addition to a C-cyclopropylaldonitrone, C-[cis-2-(N,N-diethylcarbamoyl)-trans-2-phenylcyclopropyl]-N-benzylaldonitrone (1), stereoselectively gave the anti-product 3, in which the stereoselectivity was particularly high when MgBr(2) was the additive. In this study, the reaction pathway was investigated in detail. The stereoselective addition was initially thought to occur via either a 1,5-chelation-controlled or a bisected s-trans conformation-controlled pathway. However, Grignard addition to a nonchelating silyl ether-type substrate, C-[cis-2-(tert-butyldiphenylsilyloxymethyl)-trans-2-phenylcyclopropyl]-N-benzylaldonitrone (7), also gave the anti-product 9 with high stereoselectivity suggesting that chelation is not important in the reaction. Theoretical calculations of C-cyclopropylaldonitrones showed that the coordination of Mg(2+) at the nitrone oxygen significantly stabilizes the bisected s-trans conformer due to the effective hyperconjugation between the pi* of the nitrone C=N bond and the electron-donating cyclopropane orbitals. This kind of orbital interaction is able to stabilize the transition state of the nucleophilic addition and is maximized in the bisected conformation, in which the orbitals of the forming bond and the cyclopropane C-C bond are in an almost planar arrangement. Thus, the high stereoselectivity can be explained by nucleophilic attack on the less hindered side of the C=N bond of the substrates in the Mg(2+)-coordinated bisected s-trans conformation.

Abstract
The stereoselective hydride reduction of the cis- and trans-substituted cyclopropyl ketones was systematically investigated using a series of structurally simplified substrates, trans-[tert-butyldiphenylsilyloxymethyl]cyclopropyl ketones 1a-e and trans-(benzyloxymethyl)cyclopropyl methyl ketone (2), and the corresponding cis congeners 3a,b,e and 4. The results showed that, not only in the reduction of the cis-substituted cyclopropyl ketones but also in that of the trans-substituted ketones, high stereoselectivity can be realized when the substrate has a bulky substituent on the cyclopropane ring, even though it is attached to the position trans to the acyl moiety. Ab initio calculations based on the density functional theory (DFT) of cyclopropyl ketones showed that (1) the bisected s-cis and s-trans conformers were the only two minimum energy conformers, while the s-cis conformer was more stable than the s-trans and (2) a bulky alkyl group in the acyl moiety and a cis substituent on the cyclopropane ring made the bisected s-cis conformer much more stable. On the basis of these calculations and experimental results, it is likely that the more stable the bisected s-cis conformer of the substrate, the more stereoselective the hydride reduction. Thus, the stereochemistry can be explained by hydride attack on the bisected s-cis conformation of the substrate from the less-hindered face. The predictability of the stereochemical results is predicated on the bisected s-cis transition-state model, which is very important from the viewpoint of synthetic organic chemistry.

Abstract
Phosphoric esters of secondary alcohols are ubiquitous in biological systems. However, despite the obvious interest of the corresponding difluoromethylene phosphonates as isopolar mimics, a single example of such an analogue featuring this particular substitution pattern has so far been reported in the literature, due to synthetic problems associated with their preparation. The lithium salt of diethyl difluoromethylphosphonothioate 28d provides a solution to this problem, as demonstrated by an 8-step synthesis of all five fully protected analogues of nucleoside 3'-phosphates in 9-18% overall yield, from readily available ketones. Sulfur is shown to play a crucial role in the introduction of the phosphorus-substituted difluoromethylene unit onto the furanose ring. Complete diastereoselectivity is observed in the three steps of the process requiring stereocontrol. The key conversion of the P=S bond into its oxygenated analogue is simply achieved by use of m-chloroperoxybenzoic acid. It is noteworthy that the synthesis can be carried out on large scale: a 31-g batch of compound 26b has been prepared. The deprotected nucleoside 3'-phosphate analogues can be liberated from their precursors as exemplified by the conversion of 7b, 8b, and 9b into the corresponding difluorophosphonic acids, isolated in the form of their disodium salts.
