An efficient approach for the synthesis of a fully functionalized 7-aminoaziridinomitosene has been developed Commencing with the known 2,3,5,6,7,8-hexahydro-8-oxo-1H-pyrrolo[1,2-a]indole 6, twelve transformations leads to the novel 7-amimoaziridinomitosene 4 in 11% overall yield. This study demonstrates the feasibility of installing the free aziridine and the aminoquinone functionalities on the pyrrolo[1,2a]indole skeleton. (C) 1997 Elsevier Science Ltd.
