[摘要]：Pd(0) catalyst promotes three-component coupling reactions of allylic alcohols and vinylcyclopropanes with terminal alkynes and triethylborane to provide (E)-1-substituted 2-ethyl-1,4-pentadienes and (E)-1-substituted 2-ethyl-1,4-heptadienes involving geminal ethylation and allylation at the acetylenic terminal carbon atom with high regio- and stereoselectivities. 1,3-Butadiene and bis-dienes can act as allylating agents to undergo the multi-component coupling reactions, accompanied by dimerization of the diene moieties, to provide 1,4,9-decatrienes and pyrrolidines with excellent regio- and stereoselectivities. |
