Symmetrical anhydrides were synthesized from activated amides such as N-benzoylsaccharins and N-Boc-protected benzamides. The activated amides reacted with H2O in the presence of 1,4-diazabicyclo[2.2.2]octane (DABCO) at 25 °C to produce the corresponding symmetrical anhydrides in high yields through C–N bond cleavage. In addition, N-benzoylsaccharins reacted with benzoic acid derivatives to generate
对称酸酐由活化的酰胺合成,例如N-苯甲酰糖精和N -Boc-保护的苯甲酰胺。活化的酰胺在 1,4-二氮杂双环 [2.2.2] 辛烷 (DABCO) 存在下于 25 °C 与H 2 O 反应,通过 C-N 键裂解以高产率产生相应的对称酸酐。此外,N-苯甲酰糖精与苯甲酸衍生物反应生成不对称酸酐,产率高。
