Lipase-mediated kinetic resolution of cis-1,2-indandiol and the Ritter reaction of its mono-acetate
摘要:
Lipase-mediated kinetic resolution of cis-1,2-indandiol 5 in the presence of lipase PS was examined. Enantiomerically enriched (1S,2R)-2-acetoxy-1-indanol 6a was obtained when cis-1,2-indandiol 5 was treated with one equivalent of vinyl acetate. Treatment of 5 with two equivalents of vinyl acetate furnished a mixture of (1R,2S)-2-acetoxy-1-indanol 6a and (1R,2S)-1-acetoxy-2-indanol 6b. A route to both enantiomers of a was also developed by using the enantiomerically enriched mono-acetate thus obtained. (C) 2001 Published by Elsevier Science Ltd. All rights reserved.
