Herein, we report on the unprecedented dimerization of 1,6-enynes using a commercially available ruthenium complex RuCl2(PPh3)3, which results in a series of bicyclo[3.1.0]hexyl allene derivatives in moderate to excellent yields. Mechanistic investigation indicates that the in-situ-generated ruthenium vinylidene undergoes a site-selective metathesis process to provide allenyl ruthenium carbene, which can be intramolecularly trapped by the pendent C=C bond of enyne through a [2 + 2] cycloaddition/metal elimination process.

An efficient Cu(I)-catalyzed oxidative cyclization of alkynyl-tethered enynamides for the construction of fused bicyclic cyclopentadiene derivatives is disclosed. The cascade proceeds through alkyne oxidation, carbene/alkyne metathesis, and formal (3 + 2)

, p. 4310 - 4320 (2016/01/29)
In this study, a series of novel amide derivatives and sulfamide derivatives as potential E. coli PDHc E1 inhibitors were designed and synthesized by optimizing the linker between triazole and benzene ring moieties based on the structure of lead compound
Titanium(IV) chloride-mediated carbocyclization of 1,6-Enynes: Selective synthesis of 3-Azabicyclo[3.1.0]hexanes and functionalized allenes by controlling the reaction temperature
Zhang, Zhen,Shi, Min
, p. 2610 - 2614 (2011/06/28)
1,6-Enynes can be transformed into 3-azabicyclo[3.1.0]hexanes and functionalized allenes in moderate to good yields along with moderate to high diastereoselectivities by controlling the reaction temperature in the presence of titanium(IV) chloride. A plausible mechanism is proposed. 1,6-Enynes can be transformed into 3-azabicyclo[3.1.0]hexanes and functionalized allenes respectively in moderate to goodyields along with moderate to high diastereoselectivities by controlling the reaction temperature in the presence of titanium(IV) chloride. A plausible mechanism is proposed.
Synthesis of trisubstituted pyrroles from rhodium-catalyzed alkyne head-to-tail dimerization and subsequent goldcatalyzed cyclization

Dimerization of N-protected propargylic amines in a rather rare head-to-tail mode has been achieved under mild conditions with high selectivity using rhodium catalysts. The JV-protecting group could be a sulfonyl, carbamate, or carbonyl functionality and
