Article abstract of DOI:10.1021/jo00186a032

An investigation of the intramolecular Diels-Alder reaction of 1,2-diazines and the application of this cycloaddition to a general synthesis of indolines is described.The use of this cycloaddition in a short, regiospecific preparation of the 1,2-dihydro-3H-pyrrolo<3,2-e>indole skeleton, the structural subunit characteristic of the antitumor antibiotic CC-1065, is detailed.
