Palladium-Catalyzed Approach to the Synthesis of S-heterocycles

Heterocyclic compounds containing sulfur atom is an important division of compounds which play important role in new drug development. The S-heterocycles synthesis and their chemical and biological behavior have received much importance in past recent decades. This article focuses on the applications of palladium catalysts for the synthesis of heterocylces with sulfur atom. This article covers mostly literature published during the period from 1970–2015. It describes the synthetic pathways to different sized heterocyclic rings.
