Palladium(0)-Catalyzed Diastereoselective (3+2) Cycloadditions of Vinylcyclopropanes with Sulfonyl-Activated Imines

Abstract

We report herein a palladium(0)-catalyzed (3+2)-cycloaddition process between vinylcyclopropanes and cyclic or acyclic sulfonylimines. This reaction, which operates under low catalyst loading and practical reaction conditions, gives access to a wide variety of N-heterocyclic derivatives in good to excellent yields and high levels of diastereoselectivity.
