  one-pot reaction sequence starting from prochiral α-chloroketones leading to enantiopure β-azidoalcohols and β-hydroxynitriles is described. Asymmetric bioreduction of α-chloroketones by hydrogen transfer catalysed by an alcohol dehydrogenase (ADH) established the stereogenic centre in the first step to furnish enantiopure chlorohydrin intermediates. Subsequent biocatalysed ring closure to the epoxide

  AbstractA gene encoding halohydrin dehalogenase from an alphaproteobacterium (AbHHDH) was identified, cloned and over-expressed in Escherichia coli. AbHHDH was able to catalyze the stereoselective dehalogenation of prochiral and racemic halohydrins. It showed the highest enantioselectivity in the dehalogenation of 20 mM (R,S)-2-bromo-1-phenylethanol, which yielded (S)-2-bromo-1-phenylethanol with 99%

• Azidolysis of epoxides catalysed by the halohydrin dehalogenase from Arthrobacter sp. AD2 and a mutant with enhanced enantioselectivity: an (S)-selective HHDH

  Halohydrin dehalogenase from Arthrobacter sp. AD2 catalysed azidolysis of epoxides with high regioselectivity and low to moderate (S)-enantioselectivity (E = 1-16). Mutation of the asparagine 178 to alanine (N178A) showed increased enantioselectivity towards styrene oxide derivatives and glycidyl ethers. Conversion of aromatic epoxides was catalysed by HheA-N178A with complete enantioselectivity, however the regioselectivity was reduced. As a result of the enzyme-catalysed reaction, enantiomerically pure (S)-beta-azido alcohols and (R)-alpha-azido alcohols (ee >= 99%) were obtained. (C) 2016 Published by Elsevier Ltd.

  The ring opening of epoxides with nucleophiles such as TMSN3 and isopropylamine takes place enantioselectively in the presence of (beta-cyclodextrin under extremely mild conditions and the azido alcohols and amino alcohols are formed as (S)-isomers.

• Lipase-catalysed resolution of 3-(aryloxy)-1,2-propanediol derivatives — Towards an improved active site model of Pseudomonas cepacia lipase (amano PS)

  A variety of 3-(aryloxy)-1,2-propanediol derivatives with different substituents on the aromatic ring or at the primary hydroxy group were used as substrates in a kinetic resolution by transesterification with vinyl acetate catalysed by lipase from Pseudomonas cepacia (Amano PS). Derivatives with substituents in the para-position of the aromatic ring were accepted as substrates and resolved with high enantioselectivity. The corresponding derivatives with substituents in the ortho-position were much worse substrates for lipase PS or even non-substrates if the substituent was sufficiently space-filling as found for the tert-butyl, phenyl, benzyl or benzoyl residue. Otherwise, if the primary hydroxy group was substituted by unbranched long-chain acyl residues very good substrates were resulting. In contrast, derivatives with sterically crowded residues at the primary hydroxy group such as the pivaloyl, tert-butyldimethylsilyl, methanesulfonyl, para-toluenesulfonyl or trityl groups were nonsubstrates for lipase PS.
