kinetic resolution strategy capable of accessing optically active tertiary hydroperoxides is reported. Readily accessible tertiary hydroperoxides are resolved with commercially available (R)- or (S)-xylyl-PHANEPHOS with selectivity factors as large as 37. The resulting bis(phosphine oxide) can be recycled in high yields. The isolated mono(phosphine oxide) intermediate resolved hydroperoxides with the
报告了一种能够访问光学活性叔氢过氧化物的有效还原动力学拆分策略。容易获得的叔氢过氧化物用市售的 (R)- 或 (S)-二甲苯基-PHANEPHOS 拆分,选择性因子高达 37。得到的双(氧化膦)可以高产率回收。分离的单(氧化膦)中间体以与母体双膦相同的选择性拆分氢过氧化物。
