Stannyl thiolates

Stannyl thiolates were recently shown to be applicable to the formation of the macrocyclic poly-thiolactones (23) and (24), according to equation (16). ... 

Instead of thiolate anions, stannyl sulfides have been utilized, which necessitate elevated temperature during the formation of the thioglycoside, due to the lower reactivity of the stannyl derivatives. However, if a promoter (SnCH) is used, reactions at room temperature or below can be performed, this, though, also causes anomerization and alp product mixtures [59].
