Decarboxylative acylation of indolines with α-keto acids under palladium catalysis: a facile strategy for the synthesis of 7-substituted indoles†
Abstract
Palladium-catalyzed decarboxylative acylation of highly substituted indolines with α-keto acids via C–H bond activation is described. This protocol provides efficient access to C7-carbonylated indoles known to have diverse biological profiles.
