Structure of the Reaction Products from Dehydroascorbic Acid Analogues, o-Phenylenediamine, and Arylhydrazines. X-Ray Molecular Structure of 3-quinoxalin-2(1H)-one Hemihydrate

Acetylation of the product obtained from successive reaction of dehydro-L-ascorbic acid with o-phenylenediamine and phenylhydrazine gave 3-quinoxalin-2(1H)-one (3) rather than the cyclic structure (4) previously assigned for the reaction product.The structure of compound (3) was confirmed based on 1H NMR, 13C NMR, and X-ray analysis.Reinvestigation of the reaction of 5-phenylfuran-2,3,4(5H)-trione (6) with o-phenylenediamine and an arylhydrazine led to the isolation of two compounds (7) and (10).The former was found to exist in dimethyl sulphoxide solution as a tautomeric mixture of hydrazone imine and diazenyl enamine.Attempted acetylation of compound (7) afforded the furoquinoxaline ring system (8).
