Abstract

An efficient synthesis of 4,5-disubstituted thiazoles via base-induced cyclization of active methylene isocyanides such as tosylmethyl isocyanide, ethyl isocyanoacetate, and arylmethyl isocyanides with methyl arene- and hetarenecarbodithioates is reported. This synthesis could be a new click chemistry reaction, since it is simple, rapid, and often avoids purification steps. In addition, this method allow us a clear and general synthesis of novel 4,5-diarylthiazoles.
