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 acyclonucleosides via allylation of 3-[1-(phenylhydrazono)-L-threo-2,3,4-trihydroxybut-1-yl]quinoxalin-2(1H)one

The allylation of 3-[1-(phenylhydrazono)-L-threo-2,3,4-trihydroxybut-1-yl] quinoxalin-2(1H)one (1) gave, in addition to the anticipated 1-N-allyl derivative (2), a dehydrative cyclized product, 1-N-allyl-3-[5-(hydroxymethyl)- 1-phenylpyrazol-3-yl]quinoxal
