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.
N'-烷基和N-苯基取代的硫脲与N-取代基β-位上的羟基与亚硫酰氯反应,通过氧化环化反应得到苯并噻唑衍生物;没有形成其他产物,例如噻唑啉或恶唑啉。各种光谱和化学数据证实了该结构。
