ABSTRACT A new, simplesynthesis of succinimides is described. The reactions were carried out under the ultimate green conditions excluding both catalyst and organic solvent by applying simple stirring at 100 °C. A wide variety of N-susbstituted succinimides have been prepared in high yields by using succinic acid and primary amines in hot water. Yield of N-alkyl substituted succinimides were found
摘要描述了一种新的、简单的琥珀酰亚胺合成方法。反应在最终绿色条件下进行,不包括催化剂和有机溶剂,在 100 °C 下进行简单搅拌。已经通过在热水中使用琥珀酸和伯胺以高产率制备了多种 N-取代的琥珀酰亚胺。发现N-烷基取代的琥珀酰亚胺的产率高于N-芳基取代的琥珀酰亚胺的产率。图形概要
Access to Polycyclic Indole-3,4-Fused Nine-Membered Ring via Cascade 1,6-Hydride Transfer/Cyclization
4-fused skeleton. Aldehyde serves as a key to start the whole process, including 1,6-hydride transfer enabled δ-C(sp3)–H activation of the secondary amine. The challenges of construction of medium-sized rings are addressed via hydride transfer chemistry.
The present invention provides compounds that are effective against inhibiting topoisomerase (i.e., topoisomerase I and/or topoisomerase II). These compounds are used for treating cell-proliferative disorders. In some instances, these compounds have anticancer activity, e.g., against multi-drug resistant cancers.
