Abstract

Enhanced steric congestion of an indolyl-derived phosphine ligand enables a Pd-catalyzed mono-α-arylation of aryl- and heteroarylketones with aryl mesylates and tosylates. This protocol is suitable for modifications of biological phenolic compounds, rendering it amenable for functionalization of phenolic (pro)drugs.
