One-pot synthesis of sulfur heterocycles from simple organic substrates

Abstract

Sulfur-nitrogen heterocycles are important compounds due to their unusual physical properties and significant and versatile biological activity. A novel strategy for their preparation from readily available organic substrates with the employment of sulfur monochloride is proposed. A synthesis of wide range of heterocyclic systems including 1,2-dithioles, 1,2,3,4,5-pentathiepins, 1,2,3-dithiazoles, 1,4-thiazines, 1,2,3,4,5,6,7-heptathiocanes and others, in a cascade transformations has been developed.
