with simultaneous carbon-sulfur bond formation and carbon-hydrogen bond cleavage at the transition state. The sulfinamide adducts can be transformed by 2,3 sigmatropicrearrangement of a derived sulfoxide into optically active allylic alcohols. Thus, the overall transformation effects allylic hydroxylation with high levels of regio- and absolute stereochemical control

The 2-methylbut-2-enyl(diphenyl)silyl group can be introduced into a variety of organic structures by way of the cuprate reagent 4, and it can then be converted into a hydroxyl group, even in the presence of a C=C double bond, unlike the dimethyl(phenyl)silyl group.
