Chemoenzymatic preparation of optically active β-amino-cyclohexanols and their application in the enantioselective addition of diethylzinc to benzaldehyde
摘要:
Optically active vesamicol and other trans-2-(N,N-dialkylamino)cyclohexanols have been easily prepared in a two step sequence: opening of the oxirane ring of cyclohexene oxide with a secondary amine and subsequent resolution of the resulting racemic amino alcohol by transesterification catalyzed by Pseudomonas ccpacia lipase. The utility of these beta-aminocyclohexanols as chiral ligands in the enantioselective addition of diethylzinc to benzaldehyde has also been investigated. (C) 2004 Elsevier Ltd. All rights reserved.
