A chemoselective C−O bond cleavage of the ester alkyl side‐chain of α‐acyloxy ketones was realized for the first time by a highly efficient palladium‐catalyzed hydrogenolysis (S/C=6000, the highest catalytic efficiency by far). Furthermore, a kinetic resolution of α‐acyloxy ketones was first developed by enantioselective hydrogenolysis with good yields and up to 99 % ee.
通过高效钯催化的氢解反应(S / C = 6000,迄今为止最高的催化效率),首次实现了α-酰氧基酮的酯烷基侧链的化学选择性C-O键断裂。此外,首先通过对映选择性氢解反应开发了α-酰氧基酮的动力学拆分方法,该方法具有良好的收率和高达99%ee的收率。
