(SAR) is given. In an attempt to explain the selective action on the mechanism of 5-hydroxytryptamineuptake by the newinhibitors, their structures are compared with those of the two neurotransmitters. From the tentative pharmacophore and conformations of transmitter (5-HT) and inhibitor (alaproclate) derived from SAR, a hypothetic carrier site for 5-HT uptake is deduced in terms of geometry and electronic

can be prepared diastereoselectively starting from racemic α-bromo acids, and undergo epimerisation under appropriate conditions leading to an enhanced d.e.. By reacting the individual isomers, or in some cases the mixture of diastereoisomers, with a suitable nucleophile it is possible to obtain α-substituted carboxylic acidderivatives in diastereomerically enriched form.
