Cyclobutanone dimethyl dithioacetal

In addition to the application of malonic esters, four-membered ring compounds can also be realized by using methyl methylsulfanylmethyl sulfoxide (14) as the active methylene component.25 27 As demonstrated in the following scheme, when the potassium salt of methyl methylsulfanylmethyl sulfoxide is allowed to react with 1,3-dibromopropane, cyclobutanone dimethyl dithioacetal 5-oxide (16) is isolated in 97% yield.8,10 Of particular interest is that the...
