role for vinyl boronates: Vinyl boronate esters are well known as synthons for ketones and for their ability to participate in cross‐coupling reactions. A tandem oxidation is introduced to convert 2‐B(pin)‐substituted allylic alcohols into 2‐keto‐anti‐1,3‐diols with high diastereoselectivity. Under these reaction conditions, the vinyl boronate ester is now a synthon for α‐hydroxy ketones.
