Chelation(SnCl4)-controlled carbonylâene reaction of 2-benzyloxypropionaldehyde with vinyl sulfides is shown to provide a stereodivergent route to chelation-erythro and -threo diastereoisomers of steroid (brassinolide) side chains via the nickel-catalysed coupling reaction of the vinyl sulfide products.
