The Enantioselectivity of the biohydrolysis of sec -alkyl sulfate esters using a bacterial alkylsulfatase from Rhodococcus ruber DSM 44541 was dramatically enhanced in presence of additives (‘enhancers’) such as carbohydrates, polyethylene glycol

Efficient enzymatic racemization of 2-hydroxy-2-heteroaryl-acetic acid derivatives by mandelate racemase under mild conditions is reported for the first time. (i) Steric limitations for aryl-substituted mandelate derivatives were elucidated to be par

A practical and short synthesis of the enantiomerically pure dihydropyrimidone antihypertensive agent (R)-SQ 32926 has been developed. The key step in the synthesis is the enzymatic resolution of an N3-acetoxymethyl-activated dihydropyrimidone precur

Lyophilized cells of Rhodococcus R 312 (CBS 717.73) can be employed as an easy-to-use biocatalyst for the biocatalytic hydrolysis of nitriles to furnish the corresponding carboxamides or acids on a preparative scale. The following practical aspects a

Biocatalytic techniques, which lead to the highly efficient transformation of a racemate into a single stereoisomeric product in (theoretically) 100% chemical yield and 100% enantiomeric excess are reviewed and their specific merits and limitations a

Deracemization of (±)-mandelic acid was achieved by using a novel two-enzyme process consisting of: (i) Pseudomonas sp. lipase catalyzed O-acylation of (±)-mandelic acid in diisopropyl ether; followed by (ii) mandelate racemase catalyzed racemizati
