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.

The title β-alkylation is achieved through a sequence of sulfenylation of α-enal acetals, t-BuLi-promoted alkylation, and oxidative hydrolysis.
