Synthesis of 9,9-Disubstituted 9H-Pyrrolo[1,2-a]indoles by Hydriodic Acid-Catalyzed Cyclization of 1-[2-(1-Aryl(or methyl)ethenyl)phenyl]-1H-pyrroles
摘要:
AbstractA novel method is reported for the synthesis of 9,9‐disubstituted 9H‐pyrrolo[1,2‐a]indoles. Cyclization of 1‐[2‐(1‐aryl(or methyl)ethenyl)phenyl]‐1H‐pyrroles, which can be easily prepared from 2‐(1‐aryl(or methyl)ethenyl)anilines, proceeds smoothly, in general, at 0° in the presence of a catalytic (or an equimolar) amount of HI in MeCN to provide the desired products.
