Abstract
The reaction of N′-alkyl and N-phenyl substituted thioureas with a hydroxyl group at the β-position of the N-substituent with thionyl chloride gave benzothiazole derivatives by an oxidative cyclization reaction; no other products, such as thiazolines or oxazolines, were formed. The structure was confirmed by the various spectral and chemical data.Keywords
