spectroscopy. Moleculardocking are used to study the anticancer activity of the most active compounds. Moleculardocking of the molecule 3 into the AKR1C1 crystal structure reveals the key interactions with the active site. The theoretical calculations for the compounds 3a-3e were performed using DFT/B3LYP/6-31 G (d,p) method. The optimized structural parameters, Frontier molecular orbitals (FMO's)
GRAPHICAL ABSTRACT ABSTRACT An efficient protocol was developed for the synthesis of N-sulfonylimines under environment friendly conditions. Ultrasonic energy was employed to obtain the desired products in excellent yields with high purity under solvent- and catalyst-free conditions. The synthesis of new N-sulfonylimines was accomplished from various N-sulfonamides and benzaldehyde. The structures
图形摘要 摘要 开发了一种在环境友好条件下合成 N-磺酰亚胺的有效方案。在无溶剂和无催化剂的条件下,采用超声波能以高产率和高纯度获得所需产品。新的N-磺酰亚胺的合成是由各种N-磺酰胺和苯甲醛完成的。合成化合物的结构通过元素分析以及 1H、13C NMR 光谱数据、IR 和 MS 确认。
