yl pyrrole with heterocumulenes leads to functionalized pyrrolo[l,2-a]quinoxalines. Iminophosphorane , derived from 2-(o-amino)phenyl indole, reacts under mild conditions with isocyanates to form which are converted into 5-amino-11H-indolo[3,2-c]quinolines . Iminophosphorane 19 also reacts with carbon dioxide and carbon disulfide to give indolo[3,2-c]quinolines . Iminophosphorane . derived from 2-
亚氨基正膦N- [邻-(三苯基正膦亚基)氨基]-苯基吡咯与杂枯烯的氮杂-维蒂希反应导致官能化的吡咯并[1,2-a]喹喔啉。衍生自2-(邻氨基)苯基吲哚的氨基磷烷在温和的条件下与异氰酸酯反应生成异氰酸酯,然后将其转化为5-氨基-11H-吲哚并[3,2-c]喹啉。亚氨基磷烷19还与二氧化碳和二硫化碳反应以产生吲哚[3,2-c]喹啉。亚氨基磷烷。从2-FO-叠氮基) -苯基-3-苯基吲哚衍生的,与异氰酸酯,二氧化碳和二硫化碳反应形成吲哚并[1,2-C] -quinazolines和分别。
