Abstract
We report herein the asymmetric total synthesis of periglaucines A-C, N,O-dimethyloxostephine and oxostephabenine. The key strategies used include: 1) a RhI -catalyzed regio- and diastereoselective Hayashi-Miyaura reaction to connect two necessary fragments; 2) an intramolecular photoenolization/Diels-Alder (PEDA) reaction to construct the highly functionalized tricyclic core skeleton bearing a quaternary center; 3) a bio-inspired intramolecular Michael addition and transannular acetalization to generate the aza[4.4.3]propellane and the tetrahydrofuran ring.

Abstract
The synthesis of both enantiomers of 3-[(tert-butyldimethylsilyl)oxy]methyl-4,5-O-isopropylidenecyclopent-2-en-1-ol was accomplished in six steps based on optically inactive dimethyl meso-tartrate. This key intermediate in the synthesis of cyclopentenyl carbocyclic nucleosides was subsequently applied in the preparation of enantiomeric neplanocins A. The toxic effect of these compounds was investigated for a series of suspension and adherent cancer cell lines and normal human fibroblasts. (-)-Neplanocin A ((-)-NPA) was more toxic against all tested cancer cell lines than its dextrorotary counterpart. The highest toxicity with IC50 values of 7 and 10 μM was observed for the MOLT-4 and A431 cells, respectively. Moreover, (-)-NPA also induced apoptosis in A431 cell while this effect was not observed for (+)-NPA.

Abstract
Highly enantio- and diastereoselective phosphine-catalyzed [3+2] cycloadditions of terminal allenoates with β-perfluoroalkyl α,β-enones leading to a range of trifluoromethylated cyclopentenes with two contiguous chiral centers (up to 99% yield with 99% ee) have been developed. Moreover, these reactions could be performed at the gram scale by using only 1 mol% catalyst. The method developed here was also applied to the concise synthesis of trifluoromethylated DGAT-1 inhibitor.

Abstract
Intramolecular tandem seleno-Michael/aldol reaction followed by an oxidation-elimination process can be an efficient tool for the construction of hydroxy cyclo-1-ene-1-carboxylate esters from oxo-α,β-unsaturated esters. Generation of lithium selenolate from elemental selenium and n-BuLi provides a simple and efficient one-pot access to cyclic endo-Morita-Baylis-Hillman adducts.

A brief, enantioselective synthesis of a hydroxymethyl-cis-1,3-cyclopentenediol building block is presented. This scaffold allows access to the cis-1,3-cyclopentanediol fragments found in a variety of biologically active natural and non-natural products. This rapid and efficient synthesis is highlighted by the utilization of the palladium-catalyzed enantioselective allylic alkylation of dioxanone substrates to prepare tertiary alcohols.

Abstract
The structure elucidation of (+)-amphidinolide A, a cytotoxic macrolide, has been accomplished by employing a combination of total synthesis and NMR spectroscopic analysis. Amphidinolide A possesses two skipped 1,4-diene subunits which are accessible by ruthenium-catalyzed alkene-alkyne couplings. Previous total syntheses had revealed that the reported structure was incorrect; therefore, to incorporate maximum flexibility into the synthesis, with the ultimate goal of determining the correct structure, a highly convergent approach was chosen. Furthermore, liberal use was made of catalytic asymmetric transformations to set individual stereocenters. Three different strategies were envisioned for the end game, and due to the highly convergent nature of the synthesis, all three routes disconnect to the same three key intermediates, 5, 6, and 7. Diastereomers of 6 and 7 were easily prepared by modification of the synthetic routes to allow access to multiple diastereomers of 1 for structural determination.

Abstract
The product distribution upon conjugate addition of homochiral lithium N-benzyl-N-alpha-methylbenzylamide to dimethyl-(E,E)-nona-2,7-dienedioate can be controlled to give either the cyclic 1,2-anti-1,6-anti-beta-amino ester (derived from conjugate addition and intramolecular enolate cyclisation) or the acyclic bis-beta-amino ester derivative (derived from double conjugate addition) in high de. The introduction of a protected nitrogen functionality into the diester skeleton facilitates, after conjugate addition and intramolecular enolate cyclisation, the asymmetric construction of piperidines in high de; variation in the N-protecting group indicates that the highest stereoselectivity is observed with alpha-branched N-substituents. Tandem conjugate addition-aldol reactions can also be achieved stereoselectively, with lithium amide conjugate addition to epsilon- and zeta-oxo-alpha,beta-unsaturated esters giving the corresponding five and six membered cyclic beta-amino esters in high de. N-deprotection by hydrogenolysis of the products arising from these reactions furnishes a range of polyfunctionalised transpentacin and transhexacin derivatives in high de and ee.

Abstract
Treatment of formylalkenoates 1 and 7 with 2,2'-azobis(2-methylpropanenitrile) (AIBN) in the presence of dioxygen gave oxygenated carboxylic acids 5, 6, 8, 9 instead of acyl radical cyclization products, through preferential reaction of the corresponding acyl radicals with dioxygen rather than intramolecular attack to an enoate moiety. The reaction of 1 with AIBN in the absence of dioxygen recovered starting 1 in 98% yield.

Abstract
A simple synthesis of chiral spironucleosides and spirobisnucleosides is described. Intramolecular 1,3-dipolar nitrone cycloaddition reaction of d-glucose-derived precursors having olefin at C-3 and nitrone at C-5, C-1, or C-2 (in nor-series) furnished bisisoxazolidinospirocycles 4-7, 11, and 12 in good yields. Reductive ring opening of the isoxazolidine moieties in 4-6 followed by construction of a nucleoside base upon the generated amino groups smoothly yielded spirobisnucleosides 17 and 18 and spironucleosides 20 and 21.

Abstract
Nitrogen-functionalized cyclohexane derivatives with three contiguous chiral centers were synthesized by nitroalkene-selective conjugate addition of phenyllithium to a omega-nitro-alpha,beta,psi,omega-unsaturated ester and subsequent stereocontrolled intramolecular nitro-Michael cyclization with cesium fluoride and a quaternary ammonium bromide. The cyclohexanes were applicable to the total synthesis of alpha-, beta- and gamma-lycoranes.

Abstract
As a part of our studies aimed at asymmetric catalytic reactions by using an external chiral ligand, we have developed a catalytic asymmetric addition reaction of an arylthiol to alpha,beta-unsaturated esters under the control of an external chiral ligand. The characteristic of our technology is a double activation of a thiol by lithiation and chelate formation with a chiral tridentate amino diether ligand, which simultaneously and effectively controls a stereochemistry of the reaction. One significant feature of an arylthiol is a bulky 2-substitution on aryl group, which enables the formation of a really reactive monomeric thiolate species. s-Cis conformation and capability of electron lone pair-differentiating coordination of a carbonyl oxygen to lithium are structural requirements of the substrates for high enantioselectivity. The enantioselectivity came up to 97% under the cited conditions. Asymmetric protonation of a transient enolate, generated by conjugate addition of a lithium thiolate to an enoate, was also realized. The stereochemistry of the protonation was controlled by the conformation of initially formed transient enolate in a 1,2-asymmetric induction manner. This technology enabled the asymmetric synthesis of (S)-naproxene. Stereoselective tandem C-S and C-C bond-forming reaction was developed as a logical extension by trapping the transient enolate intermediate with an aldehyde as a carbo-electrophile in the presence of phenylthiotrimethylsilane as an equilibrium-shift reagent. This tandem reaction was extended to a stereoselective cyclization of omega-oxo-alpha,beta-unsaturated esters initiated by a lithium thiolate. Stereoselectivity of both tandem inter- and intramolecular reaction is predictable by an allylic strain-controlled conformation model of the enolate, in which an approach of aldehyde takes place anti to C-S bond through coordination of an aldehyde oxygen to lithium. Total synthesis of (-)-neplanocin A was achieved by using the tandem cyclization as a key tool for the direct construction of a five-membered carbocycle where every carbon is functionalized.

Abstract
An improved method for the synthesis of enantiomerically pure D-cyclopentenyl nucleosides has been accomplished and their antiviral activity against orthopox viruses have been evaluated. The key intermediate, L-cyclopent-2-enone 13 was prepared from D-ribose using a ring closing metathesis reaction in eight steps. Among the synthesized nucleosides, the adenine 2 (Neplanocin A), cytosine 14, and 5-F-cytosine 15 analogues exhibited potent anti-orthopox virus activity, including smallpox virus.
