The compound II is obtained by condensation of the tetramesylate Ic with sodium diethyl malonate in toluene. The dithiacompounds III and V are formed by refluxing of Ic respectively 1,1,2,2-tetrakis-hydroxymethyl-cyclobutane-tetramesylate with Na2S ∙ 9 H2O in dioxane/ethanol. The oxydation of III with H2O2 in acetic acid gives the tetrahydrothiapyrane-derivate IV.
