| Abstract: | The N--acylation of amine, O--acylation of alcohol and the selective N--acylationof the aminoalcohol with the active diamides of tetrahydrothiazole--2--thione werestudied. A series of polyamides, hydroxyl polyamides and polyesters had beensynthesized using the polycondensation of the active diamides with the aliphaticdiamines, 1, 3--diamino--2--propanol and diols under mild conditions. Furthermore,chemoselective polyamidation was achieved from multifnnctional aminoalcohol andactive diamide of tetrahydrothiazole--2--thione without special protection ofacylation--sensitive group. |
