The reactions of 1-pyridiniothiobenzoylaminides with dimethyl acetylenedicarboxylate in chloroform at 50-60 °C provided dimethyl 5-thia-2,3-diazatricyclo[,7]undeca-3,8,10-triene-6,11-dicarboxylate derivatives in moderate yields. The structures of these products were assumed by their spectral and analytical data and determined finally by the X-ray analysis of one compound.
