摘要：

It's certainly a stroke of luck that the chiral borate 2 differentiates just one isomer with high kinetic diastereoselectivity from a racemic mixture of the Grignard compound 1, which has a fluxional structure. The reaction leading to the boronic ester 3 is a combination of a racemization due to a 1,3‐metallotropic shift with the kinetic resolution of a racemate. (Figure Presented.)
