Elegant One-Pot Synthesis of Quinolino[2′,3′:7,6]-cyclohept[1,2-b]indole Through Friedländer and Pfitzinger Annulation Reaction
摘要:
A rapid, simple, and efficient method for the preparation of various quinolino[2',3': 7,6] cyclohept[1,2-b]indoles has been developed through the Friedlander and Pfitzinger condensations of 1-oxo-cyclohept[b]indole with o-amino benzophenone and isatin respectively. Reactions were performed by under different reaction conditions.
