Dimsyl anion with trithiocarbonates

In contrast, a-ketosulphoxides react with isocyanates to give the products of a monoaddition only550 (equation 290). Reaction of dimsyl anion with trithiocarbonates 481 followed by alkylation results in the formation of (methylsulphinyl)ketene dithio-acetals 482551 (equation 291).
