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?? ...
