A convergent synthetic route to the 1, 2-aziridinopyrrolo (1, 2-a) indole 34 has been developed. Key features of this route include the deuterium kinetic isotope effect to block undesired indole lithiation during tin-lithium exchange from 27a to 30a, the intramolecular Michael addition to generate the enolate 31a, and conversion into 34 by trapping with phenylselenenyl chloride. Reductive cleavage of the N-trityl group in 34 allows access to ...
