Gold(I)-catalyzed domino ring-opening ring-closing hydroamination of methylenecyclopropanes (MCPs) with sulfonamides: facile preparation of pyrrolidine derivatives.
Reaction of methylenecyclopropanes 1 with sulfonamides produces the corresponding pyrrolidine derivatives 3 in moderate to good yields under the catalysis of Au(I) via a domino ring-opening ring-closing hydroamination process.
