Abstract

Pyrimidine annulated sulfur heterocycles have been synthesized through tributyltin hydride-mediated radical reaction. This gave straight forward synthesis of tricyclic compound as well as spiro heterocyclic compounds. The reactions have been simple, straight forward and have been carried out in mild conditions.
