Article abstract of DOI:10.1016/S0040-4020(01)80569-X

With the aim of clarifying their previously incorrectly depicted structure, the indole-indoline type compounds 11 and 12 were synthesized via different routes.The results presented here are a detailed account of the synthetic aspects of this work, and also redress some points of an earlier paper on this topic.
