A MILD AND EFFICIENT TRIPHOSGENE-MEDIATED CYCLODEHYDRATION OF 2-(IMIDOYLTHIO)CARBOXAMIDES. SYNTHESIS AND CHEMISTRY OF 4-AMINO-2-(METHYLTHIO)THIAZOLIUM CHLORIDES

4-Aminothiazolium salts 1 are conveniently prepared in a one-step procedure from 2-(imi-doylthio)carboxamides 4 and triphosgene in the presence of pyridine. Their chemical reactions are discussed, including addition to dimethyl acetylenedicarboxylate and carbon disulfide in a basic heterogeneous med...
