摘要

A detailed study of the scope of a new Pd-catalyzed synthesis of indoles from 1, 2- dihaloarenes and o-halobenzene sulfonates and imines is described. The cascade reaction comprises an imine α-arylation followed by an intramolecular C− N bond-forming reaction promoted by the same Pd catalyst. The reaction with 1, 2-dibromobenzene shows wide scope and allows the introduction of aryl, alkyl, and vinyl substituents at different positions ...
