A modular approach has been developed for an efficient synthesis of an aminal group containing a new tetracyclic framework. The strategy has been devised based on selective hydrogen-bond-guided aza-Michael addition of heteroaromatic amines to cyclohexadienone-aldehydes. The reaction is highly atom economic and practical and involves stereoselective construction of four new C–N bonds and four rings
已经开发了用于有效合成包含新的四环框架的氨基基团的模块化方法。该策略是基于杂芳族胺到环己二酮-醛的选择性氢键引导的氮杂-迈克尔加成反应而设计的。该反应是高度原子经济且实用的反应,涉及四个新的C–N键和四个环的立体选择性结构。探索了四环产物的合成效用。借助实验和密度泛函理论(DFT)计算研究解释了H键的作用。
