摘要

Abstract:(Cyclooctadiene)(pentamethylcyclopentadiene) ruthenium chloride [Cp* RuClACHTUNGTRENNUNG (cod)] has been used to catalyze the regioselective cyclization of amide-tethered diynes with monosubstituted alkynes to give polysubstituted isoindolinones. Notably, the presence of a trimethylsilyl group on the diyne generally led to complete control over the regioselectivity of the alkyne cyclotrimerization. The cyclization ...
