A new approach to pyrrolophenanthridone alkaloids via intramolecular radical cyclization
A new approach to the synthesis of pyrrolophenanthridone class of alkaloids is described. The method is based on intramolecular radical cyclization of easily accessible 1-aroyl-7-bromoindoles with Bu3SnH and AIBN.
