highly enantioselective organocatalytic cascade process has been developed for the synthesis of axially chiral 1,1′-biaryl phosphorus compounds. The approach involves multistep arene formation promoted by multifunctional phosphonium salt catalysis and proceeds through a complex Thorpe-type cycloaddition/oxidative hydroxylation/aromatization cascade with central-to-axial chirality transfer.
已经开发了一种高度对映选择性的有机催化级联工艺,用于合成轴向手性 1,1'-联芳基磷化合物。该方法涉及由多功能鏻盐催化促进的多步芳烃形成,并通过复杂的索普型环加成/氧化羟基化/芳构化级联与中心到轴向手性转移进行。
