Özet

2,3-Dihydro-1H-pyrrole-2,3-diones 1a-d react with hydrazine hydrate 2 and o-phenylenediamine 4 under different conditions to yield the pyrazole-3-carboxamide derivatives 3a-d, the pyrrol-2-ones 5a-d and the quinoxaline-2-one derivatives 6a-d, respectively. Hydrolysis of the quinoxaline-2-one derivatives 6a-d gave a substituted furo[2,3-b]quinoxaline 7. The structures of the synthesized compounds were assigned on the basis of analytical results as well as spectroscopic data.
