cycloaddition of azomethine yields for synthesis of dispiropyrrolidineoxindole derivatives in hexyltriphenylphosphonium bromide as an ionic liquid, and the evaluation of their anti‐cancer activity
one-pot three-component process for the synthesis of derivatives using cycloadition catching azomethineylides in situ created by means of decarboxylative build-up of sarcosine and isatin has been developed in hexyltriphenylphosphonium bromide (HTPB) as an ionic liquid and recyclable solvent in supreme yield without the use of a catalyst underultrasonicirradiation. This method offers mild reaction conditions
在己基三苯基溴化磷 (HTPB) 作为离子液体中开发了一种绿色、轻松且具有保护性的一锅法三组分工艺,用于使用环加成反应原位捕获偶氮甲亚胺衍生物,该方法通过肌氨酸和靛红的脱羧作用生成和可回收溶剂,在超声波照射下无需使用催化剂即可获得最高收率。该方法提供温和的反应条件、在较短的反应时间内获得优异的产品收率、易于操作和环境友好的过程以及高比对和立体选择性。已针对四种细胞系研究了所有新化合物的抗癌活性。此外,这些结构还通过光谱技术和信号晶体 X 射线分析进行了验证。
