The1H and 13C NMR resonances for acridine derivatives 9‐substituted with chloro, allylamino and propargylamino groups were completely assigned using a concerted application of gs‐COSY, gs‐HMQC and gs‐HMBC experiments. 9‐(N‐Allyl)‐ and 9‐(N‐propargyl)acridinamine derivatives present amino–imino tautomerism including a large broadening of 1H and 13C NMR signals at room temperature. To obtain suitable
使用 gs-COSY、gs-HMQC 和 gs-HMBC 实验的协同应用,完全指定了被氯、烯丙基氨基和炔丙基氨基取代的吖啶衍生物的 1 H 和 13 C NMR 共振。9-(N-Allyl)- 和 9-(N-炔丙基)吖啶胺衍生物呈现出氨基-亚氨基互变异构现象,包括在室温下 1H 和 13C NMR 信号的大幅增宽。因此,为了获得合适的分辨率,在 370 K 下在 DMSO-d6 溶液中研究了这些化合物,并显示出完全向亚氨基互变异构体转变。版权所有 © 2003 John Wiley & Sons, Ltd.
