Trimethylsilyl (TMS)-substituted enynes 9-11, 13-17 and (Z)-enediynes 18 were prepared by dehydration of the TMS-substituted propargyl alcohols 1-8 with polyphosphoric acid trimethylsilyl ester.
Ruthenium-catalyzed cycloisomerization of cis-3-en-1-ynes to cyclopentadiene and related derivatives through a 1,5-sigmatropic hydrogen shift of ruthenium vinylidene intermediates

We report a new ruthenium-catalyzed cycloisomerization of unactivated cis-3-en-1-ynes, which produces substituted cyclopentadiene and related derivatives. The mechanism of this cyclization is proposed to involve a [1,5]-sigmatropic hydrogen shift of ruthenium-vinylidene intermediates on the basis of deuterium-labeling experiments. Copyright
