The ruthenium-catalyzed 1,6-enyne cyclization in the presence of bulky substituted terminal alkyne proceeds smoothly at room temperature to afford highly substituted five-membered cyclic compounds featuring a 1,5-enyne motif. Deuterium-labeling experiment
Cyclobutene formation in PtCl2-catalyzed cycloisomerizations of heteroatom-tethered 1,6-enynes

Aza(oxa)bicyclo[3.2.0]heptenes are accessed through the PtCl 2-catalyzed cycloisomerizations of heteroatom-tethered 1,6-enynes featuring a terminal alkyne and amide as the solvent. It is shown that the weak coordinating properties of the solven
Effects of substituents on the multiple bonds on ring-closing metathesis of enynes
Kitamura, Tsuyoshi,Sato, Yoshihiro,Mori, Miwako
, p. 678 - 693 (2007/10/03)
In ring-closing metathesis (RCM) reactions of enynes, the substituents on the multiple bonds are quite important. Although RCM of an enyne having a monosubstituted alkene proceeds smoothly using the first-generation ruthenium-carbene complex 1a, that of a
