A mixture of D-alloisoleucine and L-isoleucine derivatives are selectively hydrolysed by enzymatic catalysis (alcalase) allowing the recovery of the D-allo stereoisomer in excellent d.e. and yields. Thus, N-formyl-D-allo-isoleucine benzylester is obtained after enzymatic hydrolysis of the diastereoisomeric mixture or by a crystallisation procedure. (C) 2003 Elsevier Ltd. All rights reserved.
