The title aminopyrroles and thiophene have been prepared by condensation of methyl (cyanomethyl-sulfonyl)acetate with various α-amino ketones or 2-mercaptoacetaldehyde, respectively. Subsequent cyclization of these compounds by reaction between the amine and activated methylene has led to various ester-substituted thiazine- and thiadiazine-based bicyclic derivatives. In addition, cyclization of the
