Pyridine synthesis from oximes and alkynesviarhodium(iii) catalysis: Cp* and Cpt provide complementary selectivity

Abstract

The synthesis of pyridines from readily available α,β-unsaturated oximes and alkynes under mild conditions and low temperatures using Rh(III) catalysis has been developed. It was found that the use of sterically different ligands allows for complementary selectivities to be achieved.
