Herein we report a practical method for the asymmetric transfer hydrogenation/dynamic kinetic resolution of -Boc 3-fluoro-dihydrotetrahydroquinolin-4-ones into the corresponding -fluoro alcohols in 70-96% yields, up to 99:1 diastereomeric ratio (dr) and up to >99% ee (enantiomeric excess) by using the ruthenium complex Ts-DENEB and a formic acid/triethylamine (1:1) mixture as the hydrogen donor under mild conditions.
在此,我们报告了一种实用的方法,用于通过不对称转移氢化/动态动力学拆分 Boc3-氟-二氢四氢喹啉-4-酮,在温和条件下,以钌配合物 Ts-DENEB 和甲酸/三乙胺(1:1)混合物作为氢供体,以 70-96%的收率、高达 99:1 的非对映选择性比(dr)和高达>99%的对映体过量(ee)得到相应的-氟醇。
