Regio‐ and enantioselective additions of alcohols to either terminal allenes or internal alkynes provides access to allylic ethers by using a RhI/diphenyl phosphate catalytic system. This method provides an atom‐economic way to obtain chiral aliphatic and aryl allylic ethers in moderate to good yield with good to excellent enantioselectivities.
通过末端Rh I /二苯基磷酸酯催化系统,将醇的区域和对映体选择性加成到末端异戊烯或内部炔烃中,即可获得烯丙基醚。该方法提供了一种原子经济的方法,可以以中等至良好的收率以及良好至优异的对映选择性获得手性脂肪族和芳基烯丙基醚。
