A method for the highly regio- and enantioselective oxidative coupling of resorcinols has been established by using dibrominated dinuclear vanadium(V) catalyst 1c under air. When resorcinols bearing an aryl substituent were applied as substrates to the coupling, axially chiral biresorcinols were obtained as single regioisomers in high yield with up to 98% ee.
通过在空气中使用二溴化二核钒(V)催化剂1c,建立了间苯二酚的高度区域和对映选择性氧化偶联的方法。当将带有芳基取代基的间苯二酚作为底物用于偶联时,可以以高达98%ee的高收率获得轴向手性双间苯二酚作为单一的区域异构体。
