α-carbon of the chiral 4-aryl-2-piperidinone product afforded chiral trans-3,4-disubstituted 2-piperidinone derivatives and reduction of the chiral 2-piperidinones with lithium aluminum hydride provided the corresponding enantiomerically pure trans-3,4-disubstituted piperidines. This methodology has been successfully applied to the synthesis of the anti-depressant paroxetine.
