Selectivity in metal-catalyzed carbon-carbon bond cleavage of alkylidenecyclopropanes

Abstract

When more complex system leads to simpler reactivity profile; the ring-opening of strained threemembered rings such as methylene- and alkylidenecyclopropanes generally lead to several products. If one starts with more functionalized carbon skeletons, selective reactions are now observed and rationalization as well as synthetic applications are described in this concept article. This methodology could be used to the preparation of challenging structural motifs possessing quaternary carbon stereocenters in acyclic systems. © 2010 Wiley-VCH Verlag GmbH& Co. KGaA, Weinheim.
