  Gold(I)-Catalyzed Formation of Bicyclo[4.2.0]oct-1-enes

  摘要：

  Gold(I) catalysts effectively promote the Cope rearrangement of acyclic 1,S-dienes bearing a terminal cyclopropylidene. When this methodology is applied to cyclic substrates an unexpected transformation occurs, resulting in the formation of a tricyclic compound incorporating a bicyclo[4.2.0]oct-1-ene core, a portion of which is found in a number of natural products. Density functional theory calculations (M06 and M06-2X) reveal insight into the mechanism and thermodynamics of this unique transformation.
