摘要：

Cyclodehydration of racemic gamma-aryl-delta-oxoesters with (R)- or (S)-phenylglycinol stereoselectively affords bicyclic delta-lactams, in a process that involves a dynamic kinetic resolution. Subsequent reduction of these lactams leads to enantiopure 3-arylpiperidines. Starting from racemic aldehyde esters, this short sequence has been applied to the synthesis of (R)-3-phenylpiperidine and the antipsychotic drug (-)-3-PPP (an (S)-3-arylpiperidine), whereas starting from racemic ketone esters enantiopure cis-2-alkyl-3-arylpiperidines are prepared.
