摘要

A one pot synthesis of benzo [g] indolo [2, 3-a] indolizinone-5 is described. Starting from tryptamine hydrochloride and methyl o-phthalaldehydic acid ester, 85% yield is obtained in refluxing n-butanol. In spite of differences with published data, the structure of final compound has been firmly established by 2D heteronuclear correlation NMR spectroscopy.
