MAOS of quinoxalines, conjugated pyrazolylquinoxalines and fused pyrazoloquinoxalines from L-ascorbic and D-isoascorbic acid

Microwave-assisted organic synthesis (MAOS) has been used to accelerate the conversion of L-ascorbic acid (1) and D-isoascorbic acid (2) to the title heterocycles by conversion to 3-(L-threo- or D-erythro-glycerol-1-yl) quinoxaline-2-carboxylic acid o-ami

A NOVEL SYNTHESIS OF PYRIDAZINONES: PREPARATION OF 3--2(1H)-QUINOXALINONES

A novel approach for the synthesis of pyridazinones has been achieved by the reaction of α-formylhydrazones with carboethoxymethylidene triphenylphosphorane. The mode of the reaction was investigated and the structures were confirmed by both physical and
