Microwave-assisted organic synthesis (MAOS) of D-gluconic acid can be efficiently done by oxidation of D- glucose with bromine water, upon irradiation with microwave ( MW). It was also used for the conversion of D-gluconic acid to ethyl D-gluconate, D-glucono-1,4- and 1,5-lactones, gluconyl hydrazide, and gluconyl phenylhydrazide in yields comparable to those obtained by conventional methods, but in much shorter times. A convenient microwave- mediated condensation of D- gluconic acid with o-phenylenediamines provided the respective acyclonucleoside benzimidazole in short time and good yield.[GRAPHICS]
