A general synthetic approach to vinylogous 4-carboxy- and 4-keto-2,3-dihydropyrroles is reported using Ni(ClO4)(2)center dot 6H(2)O as a Lewis acid catalyst for nucleophilic amine ring-opening cyclizations of donor acceptor (D-A) cyclopropanes. This methodology provided good to excellent yields of functionalized 2,3-dihydropyrroles under milder reaction conditions than previously reported and is amenable to a variety of D-A cyclopropanes and primary amines.
