The cyclization of "Fischer-type" alkynylamino carbene chromium complexes provides a one-step regio- and diastereoselective access to tricarbonyl {4a,5,6,7,8,8a-η-[3aS*,4S*)-2, 3,3a,4-tetrahydroindeno[1,2-b]}pyrrole chromium derivatives. Based on labelling studies a mechanism is proposed which may account both for the observed C-C coupling and for the stereochemistry.
