Popis: The reaction of 2-(3-indolyl)indoline with 2-pyrrolidinone-POCl3 adducts results in the formation of 2-(3-indolyl)-1-[2-(1-pyrrolinyl)]indoles (3) which rearrange to 2,3,5,6-tetrahydro-5-(3-indolyl)-1H-pyrrolo[2.1—b] [1,3]benzodiazepines (4). The structures have been determined by NMR. MS and chemical evidence. The rearrangement proceeds in a base-catalyzed equilibrium process. Structural prerequisites for the rearrangement are discussed in terms of a proposed mechanism.
