Popis: 4-Bromo-4-formyltetrahydrothiopyrans, which were used to develop a method for the synthesis of 8,8-dialkyl-9-thia-1,4-diazaspiro[5.5]undecanes, were synthesized from 4-formyltetrahydrothiopyrans. Alkylation of these products with ethyl bromoacetate and ethyl acrylate gave, respectively, their di- and monosubstituted derivatives.
