Efficient kinetic bioresolution of 2-nitrocyclohexanol
摘要:
The kinetic bioresolution of 2-nitrocyclohexanol 1 was investigated by screening a range of hydrolases both for enantioselective transesterification and for enantioselective hydrolysis of the corresponding acetate. By appropriate choice of biocatalyst and conditions, both enantiomers of cis and trans 2-nitrocyclohexanol 1 can be accessed in enantiopure form. (C) 2010 Elsevier Ltd. All rights reserved.
