The cycloaddition of diazoazoles with acylisothiocyanates has been found to result in the formation of a 1,2,3,5-thiatriazine ring. This new reaction was used to prepare novel 8-substituted 4-[benzoylimino-4H-imidazo(pyrazolo)][5,1-d]-[1,2,3,5]thiatriazines. The structures of the compounds prepared were carefully studied by X-ray diffraction, IR and NMR spectroscopy.
研究发现,重氮唑与酰基异
硫氰酸盐进行环加成反应可形成 1,2,3,5
硫三嗪环。这种新反应被用于制备新型 8 取代 4-[苯甲酰亚
氨基-
4H-咪唑(
吡唑)][5,1-d]-[1,2,3,5]噻三嗪。通过 X 射线衍射、红外光谱和核磁共振光谱对所制备化合物的结构进行了仔细研究。
