DIARYL-2,5-OXADIAZOLES 1,3,4-HYDROXYESTER, HYDROXYACIDE AND ACETOXYACIDE, PROCESS FOR THEIR SYNTHESIS. |
| abstract |
The invention relates to 2,5-diaryl oxadiazoles-1,3,4 with hydroxy ester, hydroxy acid and acetoxyacid endings of the formula: (CF DRAWING IN BOPI) in which R1 represents a hydroxyl or acetyl radical and R2 represents a carboxyl radical and where R1 and R2 preferably simultaneously occupy the 3 and 3 'or 4 and 4' positions. The hydroxyesters are prepared by cyclization of the corresponding diaromatic dihydrazide and the hydroxy acids are obtained by saponification of the preceding hydroxyesters. |
