Abstract

An efficient, environmentally benign, and simple one-pot approach to the synthesis of 5-(iodomethyl)thiazolidine-2-thiones via multicomponent reaction of allylamines, carbon disulfide, and iodine under solvent-free conditions is presented. The obtained 5-(iodomethyl)thiazolidine-2-thiones were converted into silyl-protected­ terminal [(ethynylthio)methyl]-substituted thiazolidine-2-thiones by treatment with lithium 2,2,2-tris(trimethylsilyl)ethanedithioate, produced by the reaction of tris(trimethylsilyl)methyllithium with carbon disulfide.
