Acyclic internal alkenes are a class of challenging substrates in asymmetric Heck-type reactions due to difficulties related to both reactivity and selectivity control. Employing acyclic alkenyl alcohols, an asymmetric Heck–Matsuda reaction is developed through the strategy of chiral anion phase transfer. Various chiral ketones could be obtained in high levels of enantioselectivity. A catalytic amount
由于与反应性和选择性控制有关的困难,无环内烯烃是不对称Heck型反应中一类具有挑战性的底物。利用无环烯基醇,通过手性阴离子相转移策略发展了不对称的Heck-Matsuda反应。可以高水平的对映选择性获得各种手性酮。催化量的二甲基亚砜(DMSO)作为添加剂对于抑制氢化钯介导的副反应至关重要。
