α- and γ-substituted vinylthionium ions from SnCl4 ionisation of a range of substituted 1,3- and 3,3-bis(alkyl/phenylthio)propenes allylate enol silyl ethers in good yield. Levels of regioselectivity are sterically dependent and in the case of

The Sn-S bonds in thiostannanes, BunSn(SPh)4-n, are activated towards acetals in the presence of BF3*OEt2.Acetals of various aldehydes and ketones are converted into the corresponding monothioacetals under mild conditions.Employment of α-enal acetals induces Michael addition to give synthetically useful γ-alkoxyally sulfides.
THIOSTANNANE-MEDIATED PREPARATION OF γ-ALKOXYALLYL SULFIDES; EFFICIENT β-ALKYLATION OF α,β-UNSATURATED ALDEHYDES
Sato, Tsuneo,Okazaki, Hiroshi,Otera, Junzo,Nozaki, Hitosi
, p. 2979 - 2982 (2007/10/02)
The title β-alkylation is achieved through a sequence of sulfenylation of α-enal acetals, t-BuLi-promoted alkylation, and oxidative hydrolysis.
