Abstract

There are two general reaction pathways to realize the arylation of corresponding esters to generate α-aryl carboxylic acid derivatives reported by transition metal-catalyzed reactions (Scheme 1). Reactions via pathway (i), which involves a palladium-catalyzed coupling reaction between aryl halide electrophiles and enolates, were extensively studied by Buchwald 2, 2a, 2b, 2c, 2d, 2e and 2f and Hartwig. 3, 3a, 3b, 3c and 3d In these reactions, bulky, electron-rich ...
