Three′s not a crowd: An intramolecular [2+2+2] cyclization between three different components, allene, alkyne, and alkene, has been realized using a catalytic amount of [Cp*RuCl(cod)] complex (cod=1,5‐cyclooctadiene), and afforded fused‐tricyclic compounds in a highly stereoselective manner.
三人不拥挤:使用催化量的[Cp * RuCl(cod)]络合物(cod = 1 ,5-环辛二烯),并以高度立体选择性的方式得到稠合三环化合物。
