The cooperative palladium/l-proline-catalyzed direct α-allylic alkylation of ketones with alkynes is achieved. This reaction exhibits high atom economy since a leaving group is not liberated and a stoichiometric amount of extra oxidant is not needed. A broad range of functional groups are tolerated, and the reaction scope could be further expanded to aldehydes.
实现了炔与炔的钯/ 1-脯氨酸协同催化的直接α-烯丙基烷基化。由于不释放离去基团并且不需要化学计量的额外氧化剂,因此该反应具有高原子经济性。可以容忍各种各样的官能团,并且反应范围可以进一步扩大到醛。
