β-Carboline-directed decarboxylative acylation of ortho-C(sp²)–H of the aryl ring of aryl(β-carbolin-1-yl)methanones with α-ketoacids under palladium catalysis

Abstract

A Pd-catalysed β-carboline assisted decarboxylative acylation of <italic>ortho</italic>-C(sp²)–H of aryl ring of aryl(β-carbolin-1-yl)methanones using α-oxocarboxylic acid as the acyl ion source to form (2-aroylaryl)(β-carbolin-2-yl)methanones is demonstrated.
