The preparation of allylstannanes 1a-c, all of which bear an oxygen substituent at the allylic terminus, is desribed.These reagents react with alpha- and beta-alkoxyaldehydes in the presence of MgBr2 as Lewis acid to give SE' products with diastereofacial selectivity consistent with "chelation control"; a syn disposition of substituents about the newly formed bond is highly favored in all cases.
