Abstract

4-Alkoxymethyl-2-bromo-2-ethoxycarbonylbutanolides were obtained with good yields by  the bromination of  4-alkoxymethyl-2-ethoxycarbonylbutanolides with bromine in dry carbon tetrachloride. Reaction of the products with thiourea and aryl-substituted thioureas gave spiroheteryl-fused lactones of a new generation  –  8-alkoxymethyl-3-amino(arylamino)-7-oxa-4-thia-2-azaspiro[4,4]-2-nonene-1,6-diones.
