In this paper, LB-Phos·HBF4 salt has been applied for the Pd-catalysed Suzuki coupling reactions of optically active (Z)-α-choroalkylidene-β-lactones. Aryl, vinyl, alkyl and heteroaromatic boronic acids may be coupled with optically active β-lactones affording corresponding optically active products highly selectively and efficiently.
本文将LB-Phos·HBF 4盐用于Pd催化的旋光(Z)-α-氯亚烷基-β-内酯的Suzuki偶联反应。芳基,乙烯基,烷基和杂芳族硼酸可以与旋光性β-内酯偶联,从而高度选择性和有效地提供相应的旋光性产物。
