A new protocol for the synthesis of vicinaldiols was accomplished by the reaction of unprotected α-hydroxymethylmetals, as hydroxymethyl anion equivalents, with aldehydes. The treatment of hydroxyallylic stannanes, which were prepared from α,β-unsaturated aldehydes and Bu3SnLi in situ, with various aldehydes gave but-3-en-1,2-diols in the presence of SnCl2.
