o-Azidohetarenecarbaldehydes react with bis(trimethylsilyl)sulfide and hydrochloric acid to give fused isothiazoles in yields strongly dependent upon the nature of the heteroaromatic ring through intramolecular cyclization reaction of presumable intermediate o-azidocarbothialdehydes.
o-叠氮苯甲醛与双(三甲基硅基)硫化物和盐酸反应,经过可疑的中间体o-叠氮碳硫醛的分子内环化反应,生成的融合异噁唑产率强烈依赖于杂芳环的性质。
