Rhodium(I)-Catalyzed Stereospecific [3+2] Cycloadditions of Vinylaziridines and Ynamides

The first rhodium-catalyzed stereospecific intermolecular [3+2] cycloaddition reaction of vinylaziridines with ynamides was realized. The salient features of the transformation include broad substrate scope, mild reaction condition, and simple operation. Moreover, the chirality of vinylaziridines can be completely transferred to the cycloadducts, representing an atom-economic and enantiospecific protocol for the construction of valuable 2-amino pyrroline derivatives.
