Abstract: The gem cyano ester functionality in double Michael adduct, 4-carboethoxy-2-carbomethoxy-4-cyano-3,5-diaryltetra-hydro[2H]thiopyran-1,1-dioxide 1 has been exploited to develop three different types of spiro heterocycles viz., spiro pyrimidine, pyrazole and isoxazole derivatives in the presence of appropriate nucleophiles.
