Chemo-enzymatic preparation of optically active endo-bicyclo[4.1.0]heptan-2-ols
摘要:
Resolutions of endo-bicyclo[4.1.0]heptan-2-ols were achieved by acylation in the presence of lipase from Candida antarctica (Novozym(R)). The (1S,2R,6R) enantiomers reacted faster and the enantiomeric ratios were between 60 and 800 for the 6-substituted bicycloalkanols. (C) 1999 Published by Elsevier Science Ltd. All rights reserved.
