Abstract

magnified image

2,3‐Dihydro‐1__H__‐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.
