Coupling Reactions Between Alkynes and Alkenes

Three-Component Couplings of Alkynes, Alkenes, and Other Unsaturated Molecules 

Intramolecular Coupling of Alkynes with Enones and Vinylcyclopropanes 

Transition metal-catalyzed higher-order cycloadditions offer a powerful approach for the constmction of medium-sized rings [1]. In this context, Wender and co-work-ers have developed catalytic cycloadditions of vinylcyclopropanes with alkynes, 

135 (R = Me) with 1,3-pentadiene and AgOTf, giving rise to the bis(jt-allyl) complex
