This report introduces N‐methylpyrrolidone hydroperoxide (NMPOOH)/base as an excellent reagent system for hydroxy‐directed syn selective epoxidation of electron‐deficient olefins, characterized by high diastereoselectivity, short reaction times and remarkable chemoselectivity, especially in presence of oxidatively labile nitrogen or sulfur atoms. NMPOOH also proves efficient in the oxidation of electron‐deficient
本报告介绍了N-甲基吡咯烷酮氢过氧化物(NMPOOH)/碱,它是缺电子烯烃羟基直接合成选择性环氧化的优秀试剂体系,具有高非对映选择性,较短的反应时间和显着的化学选择性,特别是在存在氧化不稳定的氮或氢的情况下。硫原子。NMPOOH还被证明在氧化电子不足的芳族醛,去除恶唑烷酮手性助剂以及在烯烃和炔烃的官能化方面均有效,显示出广阔的应用潜力。
