Because of the formidable development of the asymmetric reduction of tetrasubstituted olefins, an effective method is in urgent demand. Herein, through the biomimetic protocol of the coenzyme NAD(P)H, the reduction of tetrasubstituted olefin 2,3-substituted 1H-inden-1-ones has been successfully realized with the catalytic chiral NAD(P)H model CYNAM, which is hard to bring about via the common rhodium
由于四取代烯烃不对称还原的巨大发展,迫切需要一种有效的方法。在此,通过辅酶 NAD(P)H 的仿生方案,利用催化手性 NAD(P)H 模型 CYNAM 成功实现了四取代烯烃 2,3-取代 1 H -inden-1-ones 的还原。通过普通的铑或铱基催化体系很难实现,以良好的收率(高达 98%)和良好的对映选择性(高达 99% ee)生产相应的产品。此外,可以从还原产物简明地合成手性生物活性分子。
