Platinum‐Catalyzed Intramolecular [4C+3C] Cycloaddition between Dienes and Allenes

Abstract

Crossing the seven C's: The three carbon atoms of several allenyl fragments can be incorporated into seven-membered carbocycles by means of a Pt-catalyzed intramolecular [4C+3C] cycloaddition with dienes (see scheme). The transformation provides a straightforward and atom-economical entry to a variety of cycloheptane-containing polycycles from readily available acyclic precursors.
