dependent on the nature of the ortho-substituent. The Aza Wittig-type reaction of iminophosphorane derived from the ortho-azido acetophenone with isocyanates and aroyl chlorides leads to the previously unreported 4-methylene-4H-3,1-benzoxazine ring. The crystal and molecular structure of 2-[2-(4-methoxybenzoylamino)phenyl]-4-methylquinoline has been established by X-Ray diffraction methods.
已经研究了几种邻位取代的芳基叠氮化物与三苯基膦的斯托丁格反应。发现反应产物强烈取决于邻位取代基的性质。衍生自邻叠氮基苯乙酮的亚氨基正膦与异氰酸酯和芳酰氯的Aza Wittig型反应可导致先前未报道的4-亚甲基-4H-3,1-苯并恶嗪环。通过X射线衍射方法建立了2- [2-(4-(甲氧基苯甲酰基氨基)苯基] -4-甲基喹啉的晶体和分子结构。
