In this report we describe an efficient synthesis of (R)-(-)-baclofen, a selective GABA(B) agonist used as an antispastic agent. Our strategy is based on an enantioselective deprotonation of a cyclobutanone easily obtained by [2+2] cycloaddition of 4-chlorostyrene and dichloroketene. (C) 1999 Published by Elsevier Science Ltd.
