Item Synthesis of various 2H-benzopyran compounds and their kinetic resolution by asymmetric hydrolysis of their racemic acetates mediated by lipases(2012-11-09) J. Y. Goujon; F. Zammattio; B. KirschlegerThe preparation of 2H-benzopyrans from bromophenols and tertiary allylic alcohols is described. The reaction is characterised by its mildness, good yields and ease of work-up. Kinetic resolution of the latter up to 95% ee was obtained by using enzyme-catalysed enantioselective hydrolysis. # 2000 Elsevier Science Ltd. All rights reserved.
