摘要：

A novel metal-catalyzed, all-alkene [2+2+2] cycloaddition reaction involving a strained and conformationally restricted bis-ene and a diene is reported.(1) Modification of the catalyst leads to competition with a diene-ene [2+2] reaction, and when an alkyne is used in place of the diene, [2+2+2] and [2+2+2+2] reactions occur involving the bis-ene and 1 or 2 equiv of the alkyne, respectively.
