In this paper, LB-Phos·HBF4 salt has been applied for the Pd-catalysed Suzukicouplingreactions 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.
