Synthesis of Pyrimidine Derivatives of Carbazolo and Azacarbazolo Fused Quinoxalines

Neelam K. Yadav | D. Kishore | Bhawani Singh

Abstract: Pyrimidine derivatives of carbazolo and azacarbazolo fused quinoxalines 11 (a-d) and 12 (a-d) have been synthesized by the cyclocondensation reactions of corresponding enol-ethers 9 (a-b) and chalcones 10 (a-b) of carbazolo and azacarbazolo fused quinoxalines with urea and guanidine nitrate respectively. The structures of all the compounds have been established on the basis of their elemental analysis and spectral (IR, 1H NMR and MS) data.
