Palladium-catalyzed dehydrogenation of dihydro-heterocycles using isoprene as the hydrogen acceptor without oxidants

Abstract

An efficient and general method for Pd-catalyzed dehydrogenative aromatization of dihydro-heteroatom compounds without external O2 and H2 is first described. The protocol firstly uses isoprene as a hydrogen acceptor. Various dihydro-heterocycles including dihydropyrimidinones, dihydropyrimidines and dihydropyridines can be dehydrogenated to produce the corresponding aromatic heterocyclic compounds.
