Nitril der trans-2-Hydroxy-cyclopentan-carbonsaeure-(1);trans-2-Hydroxycyclopentancarbonitril;trans-2-Hydroxycyclopentannitril;trans-Cyano-2-cyclopentanol;trans-2-Hydroxycyclopentane-1-carbonitrile;(1S,2R)-2-hydroxycyclopentane-1-carbonitrile
cell-catalyzed nitrilehydrolysis in one-pot. The first step, mediated by ketoreductases, involved a dynamic reductive kinetic resolution, which led to 2-hydroxycycloalkanenitriles in very high enantio- and diastereomeric ratios. Then, the simultaneous exposure to nitrile hydratase and amidase from whole cells of Rhodococcus rhodochrous provided the corresponding 2-hydroxycycloalkanecarboxylic acids with excellent

Enantiopure (1R,2R)-, (1S,2S)-, (1S,2R)- and (IR,2S)-2-cyanocyclopentanol and -cyclohexanol, isomers were prepared through the Pseudomonas cepacia lipase-catalysed acetylation of the racemic cis and trans compounds with vinyl acetate in diisopropyl ether. The quasi-irreversible nature of acylations with 2,2,2-trifluoroethyl esters is evident. (C) 1997 Elsevier Science Ltd.
