This paper is dedicated to Professor Dieter Enders on the occasion of his 70th birthday. He has always been a source of inspiration to develop new cascade reactions.

Abstract

We present a formal [3+2] cycloaddition based on synergistic catalysis. Vinylcyclopropanes derived from cyanoesters react with enals by dual activation using palladium(0) and secondary amines to form the corresponding cyclopentanes in good yields and stereoselectivities.
