Abstract
A catalytic protocol for the enantio- and diastereoselective reduction of α-substituted-β-keto carbonitriles is described. The reaction involves a DKR-ATH process with the simultaneous construction of β-hydroxy carbonitrile scaffolds with two contiguous stereogenic centers. A wide range of α-substituted-β-keto carbonitriles were obtained in high yields (94%-98%) and excellent enantio- and diastereoselectivities (up to >99% ee, up to >99:1 dr). The origin of the diastereoselectivity was also rationalized by DFT calculations. Furthermore, this methodology offers rapid access to the pharmaceutical intermediates of Ipenoxazone and Tapentadol.

Abstract
The application of hydroxynitrile lyases (HNLs) as catalysts for the stereoselective condensation of HCN with carbonyl compounds has been reported as early as 1908. This enzymatic C-C bond coupling reaction furnishes enantiopure cyanohydrins which serve as versatile bifunctional building blocks for chemical synthesis. Screening of natural sources led to the discovery of both (R)- and (S)-selective HNLs, and several distinctly different classes of these enzymes with substantial differences concerning sequence, structure, and mechanism have been found. Especially during the last two centuries, HNLs have been developed into valuable biocatalysts, which can be produced in recombinant form by overexpression in microbial hosts, resulting in the implementation of industrial processes utilizing these enzymes. Recently, protein engineering in combination with in silico methods gave rise to the development of a tailor-made HNL for large-scale manufacturing of a specific target cyanohydrin.

Abstract
(S)-Hydroxynitrile lyase from Manihot esculenta (MeHNL) was shown for the first time to be able to catalyze the enantioselective transcyanation of acetyltrimethylsilane (ATMS) with acetone cyanohydrin to form (S)-2-trimethylsilyl-2-hydroxyl-propionitrile in an aqueous/organic biphasic system. To better understand the reaction, various influential variables were examined. The most suitable organic phase, optimal buffer pH, aqueous phase content, shaking rate, temperature, concentration of ATMS, acetone cyanohydrin and crude enzyme were diisopropyl ether (DIPE), 5.4, 13% (v/v), 190 rpm, 40 degrees C, 10 mM, 20 mM, and 35 U/ml, respectively, under which the initial reaction rate, substrate conversion and product enantiomeric excess (e.e.) were 19.5 mM/h, 99.0% and 93.5%, respectively. A comparative study demonstrated that silicon atoms in the substrate had a great effect on the reaction, and that ATMS was a much better substrate for MeHNL than its carbon analogue 3,3-dimethyl-2-butanone (DMBO) with respect to the initial reaction rate, substrate conversion and product e.e. MeHNL has greater affinity towards ATMS than its carbon analogue as indicated by the much lower K(m). The activation energy of MeHNL-catalyzed transcyanation of ATMS was also markedly lower than that of DMBO. The silicon effect on the reaction was rationalized on the basis of the special characteristics of silicon atoms and the catalytic mechanism of MeHNL.

Abstract
This paper describes the stereoselective outcome of the intramolecular Diels-Alder furan (IMDAF) reaction of substituted (2S,3S)-ethanolamides 9-13, which were synthesised from a furyl substituted cyanohydrin. The latter was obtained from 2-furaldehyde with high enantioselectivity by an oxynitrilase catalysed addition of hydrogen cyanide. The stereochemistry of the IMDAF products was shown to be dependent on the size of the ethanolamide substituents R. Small substituents (H, Me, CN) gave exclusively exo-cycloaddition, whereas more bulky ones (Ph, Et) gave both evo- and endo-addition, the larger phenyl substituent giving a high endo-exo-ratio.

Abstract
Aldolization performed by addition of lithiated N-benzyl-N-tert-butylaminoacetonitrile to aldehydes provides diastereomerically pure anti-beta-hydroxy-alpha-aminonitriles. They are transformed into syn,anti-protected beta,gamma-diamino alcohols by a two-step procedure, involving addition of a Grignard reagent and reduction. The cleavage of the N-tert-butyl group is achieved by a simple acidic treatment. The application of this methodology to chiral, nonracemic aldehydes is studied. Starting from D-isopropylideneglyceraldehyde, an anti, anti, syn, anti-(2R,3S,4S,5R,6R)-diaminotriol is prepared in acceptable yield and with a good level of diastereoselectivity.

Abstract
[reaction: see text] A remarkably general lithium heteroatom assisted TMSCN or TBSCN addition to aldehydes and ketones has been discovered. The process provides excellent selectivities and high rates. Conformationally constrained ketones such as camphor, fenchone, and nopinone give excellent diastereoselectivities with TMSCN. Reduction of 2 provided diastereopure amino alcohol 3 in good yield. alpha- and beta-Methyl cyclohexanones with TBSCN-LiOR afford high diastereoselectivities and yields.

Abstract
(R)- as well as (S)-cyanohydrins are now easily available as a result of the excellent accessibility, the relatively high stability and the easy handling of hydroxynitrile lyases (HNLs). The optimization of reaction conditions (solvent, temperature, and using site-directed mutagenesis, etc.) has enabled HNL-catalyzed preparations of optically active cyanohydrins on a technical scale. The enantioselectivity of chiral metal-complex-catalyzed additions of trimethylsilyl cyanide to aldehydes has been improved, but is, by far, not yet competitive with the HNL-catalyzed reactions.

Abstract
A new synthetic route to reduced collagen crosslinks (LNL and HLNL) is described in this report. It enables an enantioselective synthesis of LNL. HLNL was obtained as a mixture of two diastereoisomers. This method also provides the possibility to introduce radio-labels during the synthesis.
