Abstract The present dissertation describes the utility of cinnamonitrilimine and related intermediates in the synthesis of ethyl N-(4-cyano-1-phenyl-3-((E)-styryl)-1H-pyrazol-5-yl) formimidate, (E)-4-imino-1-phenyl-3-styryl-1H-pyrazolo[3,4-d]pyrimidin-5(4H)-amine and (E)-4-hydrazinyl-1-phenyl-3-styryl-¹H-pyrazolo[3,4-d]pyrimidine. The latter compounds were used to synthesis of fused heterocyclic compounds. Structures of all new heterocyclic compounds were established on the basis of elemental analyses and spectroscopic (IR,¹H NMR, ¹³ C NMR, MS) studies. |
