摘要：

The ruthenium(II)-catalyzed reaction of a substituted 1,6-heptadiyne with norbornene gave a tandem [2 + 2 + 2]/[4 + 2] cycloaddition product as a single stereoisomer along with a [2 + 2 + 2] cycloadduct. CpRu-(cod)CL catalyzes both [2 + 2 + 2] cycloaddition of the heptadiyne and norbornene and subsequent [4 + 2] cycloaddition of the resultant cyclohexadiene and norbornene. The second [4 + 2] cycloaddition step was effectively improved by use of an indenyl complex, (eta(5)-C9H7)Ru(PPh3)(2)Cl, to afford the tandem adducts in moderate to good yields.
