CHEMOENZYMATIC METHODS FOR THE PREPARATION OF OPTICALLY ACTIVE CYCLIC POLYAZIDO ALCOHOLS FROM EASILY AVAILABLE ACHIRAL STARTING MATERIALS

Abstract Optically active 2,5-diazido-1,4-cyclohexanediol, 4,6-diazido-1,3-cyclohexanediol and 2,5-diazido-1,4-cyclohexanediol as precursors for polyfunctional cyclic amino alcohols were prepared by enzymatic hydrolysis of the respective butyrates with lipases from Candida rugosa (CRL), Pseudomonas cepacia (PCL), and Geotrichum candidum (GCL). The enantiomeric excesses obtained were very high.
