| 摘 要： | 以一级松香与马来酸酐的Diels-Alder加成产物马来海松酸及其进一步甲酯化产物马来海松酸甲酯为反应原料，制备了1个新型N-芳香基马来海松酸二酰亚胺.化合物的结构均经元素分析、NMR和MS表征，用COSY，HMQC和HMBC进一步对新型N-芳香基马来海松酸二酰亚胺进行结构分析，首次发现松香背景的衍生物在溶剂中能够进行构型的动力学翻转，并利用2D NMR确定了其trans和cis在溶液中的构象.

| Abstract: | Maleopimaric acid (compound 2) was formed by Diels-Alder addition of maleic acid anhydride to resin acid,then maleopimaric acid methyl ester (compound 3) was prepared by esterification of dimethyl sulfate.After maleopimaric acid methyl ester interacting with 5-Aminoisoquinoline,the N-aryl methyl maleopimaric acid diimides (compound 4) was obtained.The structures of all compounds were characterized by elemental analyses,NMR and MS.Atropisomerism was first found in compound 4 in CDCl3,and the proportion of different atropisomer(trans:cis) was calculated by 2D NMR. |

| Keywords: | atropisomerism maleopimaric acid diimide synthesis conformation |
