hydroxyalkylation of allylic N-methyl sulfoximines 1–4 gave with ≥ 95% de the anti-Z-configurated homoallylic alcohols 5–9. Lithiation of 6b and 8b with MeLi readily produced the lithiated vinylic sulfoximines (Z)-12 and (Z)-13, respectively. Ni-catalyzed substitution of (Z)-12 and (Z)-13 with PhLi and 1,5-silyl migration yielded with ≥ 98% de the disubstituted C-silylated homoallylic alcohols (Z)-14 and (Z)-15
