title: Formal [3 + 2] cycloadditions of donor-acceptor cyclopropanes and nitriles.
abstract: Donor-acceptor cyclopropanes activated with Me3SiOTf cleave to reactive intermediates that can be efficiently intercepted by nitriles in a formal [3 + 2] dipolar cycloaddition reaction. Aliphatic, aromatic, and alpha,beta-unsaturated nitriles are excellent reaction partners, giving synthetically useful 2H-3,4-dihydropyrrole cycloaddition products in high yield.
