Abstract
This paper describes the synthesis of 3-amino-3-(4-chlorophenyl)propan oic acid and the corresponding phosphonic and sulfonic acids, lower ho mologues of baclofen, phaclofen and saclofen respectively. The chlorin ated acids were all weak specific antagonists of GABA at the GABAB rec eptor, with the sulfonic acid (pA(2) 4.0) being stronger than the phos phonic acid (pA(2) 3.8) and carboxylic acid (pA(2) 3.5).
