摘要

Enantiomerically pure (3R,2'R), (3S,2'R), (3R,2'S) and (3S,2'S) alkyl-cycloalkyl-hydroxycarboxylic acid ester salts of formula (I) are new. R1 = monocyclic, bicyclic or tricyclic 3-9C cycloalkyl (optionally substituted by one or more 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl and/or halo); R2, R3 = 1-6C alkyl, 2-6C alkenyl or 2-6C alkynyl (each optionally halo substituted); Ar = 6-10C aromatic or heteroaromatic containing N, S or O; n = 1-3; A = anion of a pharmaceutically acceptable acid.
