F. Coelho et al., A SIMPLE AND EFFICIENT NEW APPROACH TO THE TOTAL SYNTHESIS OF (+ -)-4-AMINO-3-(4-CHLOROPHENYL)-BUTYRIC ACID (BACLOFEN)/, Synthetic communications, 27(14), 1997, pp. 2455-2465
Based on the utilization of a [2+2] cycloaddition reaction between dic
hloroketene and an appropriated olefin as a key step, we describe a ne
w and simple four step approach to the total synthesis of (+/-)-4-amin
o-3-(4-chlorophenyl)-butyric acid (BACLOFEN), a selective GABA(B) agon
ist used as antispastic agent.
