对映选择性平台,以促进异戊二烯化是潜在的广泛的翻译研究,由于这一主题的重要性,作为一个关键的调节生物功能。受明显缺乏用于当代药物发现的产生手性异戊二烯基片段的方法的启发,公开了通过顺序几何异构化/氢原子转移(HAT)/质子化的含有芳基酮天线的活化烯烃的光使能解偶联异构化。详细的机理分析指导了这种原子经济过程的对映选择性变体的开发(高达99%和95:5 e.r.)。重要的是,手性池准对映异构体奎宁和奎尼丁作为有效的催化剂,从而使这种除了手性药物发现模块组合对映体发散。
Enantioselective platforms to facilitate prenylation are potentially expansive for translational research due to the importance of this motif as a key regulatory of biological function. Motivated by the conspicuous dearth of methods to generate chiral prenyl fragments for contemporary drug discovery, a light-enabled deconjugative isomerization of activated alkenes containing an aryl ketone antenna is disclosed through sequential geometric isomerization/hydrogen atom transfer (HAT)/protonation. Detailed mechanistic analyses have guided the development of an enantioselective variant of this atom economical process (up to 99% and 95:5 e.r.). Importantly, the chiral pool quasi-enantiomers quinine and quinidine serve as effective catalysts, thereby rendering this addition to the chiral drug discovery module portfolio enantiodivergent.
