Abstract

A very simple method for obtaining α-arylated N-protected 2-piperidinones in high yields is described. The use of ZnCl2, ­LiHMDS or s-BuLi as the base and Pd(dba)2 as the catalyst are the key factors.

Yield calculated from aryl bromide and the unreacted N-protected 2-piperidinone was recovered.
