摘要

邻苯二酸酐在乙酸中与仲胺反应，得到2-(二乙基(或)4-烷基哌嗪或1-羰基)苯甲酸。在DMF中，以偶联剂HATU和Et3N为碱，再次与仲胺和芳胺反应，分别得到新型对称邻苯二甲酸二胺、不对称邻苯二甲酸二胺和含不对称邻苯二甲酸二胺的伯胺-仲酰胺。

Synthesis of Novel Symmetrical and Unsymmetrical o-Phthalic Acid Diamides

Phthalic anhydride was treated with secondary amines in acetic acid yielding 2-(diethyl (or) 4-alkylpiperazine or morpholine-1-carbonyl) benzoic acids. The latter were reacted, again, with secondary amines and arylamines by using the coupling reagent HATU and Et3N as a base in DMF giving the novel symmetrical o-phthalic acid diamides , unsymmetrical o-phthalic acid diamides , and primary amidic-secondary amidic containing unsymmetrical o-phthalic acid diamides , respectively.
