1,4-Dioxane as a Sacrificial Radical Buffer Enables Pd-Catalyzed Regioselective C2 Acylation of Indolyl Ketoximes: Access to 2,3-Diacylindoles and Indole-Fused Heterocycles

Abstract Pd-catalyzed regioselective C2 acylation of indoles has been achieved using a C3-ketoxime directing group and glyoxal/aldehydes. The protocol provides C2 acylated indoles with high selectivity and enables one-pot access to indole-fused pyridazines and 2,3-diacylindoles....
