Ar. Maguire et al., EFFICIENT KINETIC RESOLUTION OF 2-BENZENESULFONYLCYCLOPENTANONE DERIVATIVES, Journal of molecular catalysis. B, Enzymatic, 1(3-6), 1996, pp. 115-126
Efficient kinetic resolution of 2-benzenesulfonylcyclopentanones 1, be
aring 3-alkyl, 3-aryl, or 3-benzyl substituents, has been achieved by
bakers' yeast mediated reduction. With the unsubstituted 2-benzenesulf
onylcyclopentanone 1a, efficient asymmetric reduction to form (1S,2R)-
cis-2-benzenesulfonylcyclopentanol 2a is observed under the same condi
tions. Excellent enantioselectivities (up to > 95% eel are obtained.
