A new method for the synthesis of 4, 4-diaryl/diheteroaryl-3-butenyl derivatives of nipecotic acid as GABA transporter inhibitors is described. The key intermediates 4-tosyl-1,1-diaryl/diheteroaryl-1-butene 10a-d were synthesized by Wittig reaction, and followed by alkylation with (R)-3-piperidinecarboxylate. The resulting N-cycloalkylated amino acid esters 11a-d were saponified and then acidified to get the target compounds 1a-d. The preliminary bioassays showed that 1a-d exhibited excellent inhibition of [3H]-GABA uptake in vitro of culture cells.
