manganese‐catalyzed oxidative kinetic resolution of cyclic benzylic ethers through asymmetric C(sp3)−H oxidation is reported. The practical approach is applicable to a wide range of 1,3‐dihydroisobenzofurans bearing diverse functional groups and substituent patterns at the α position with extremely efficient enantiodiscrimination. The generality of the strategy was further demonstrated by efficient oxidative kinetic
据报道,锰通过不对称的C(sp 3)-H氧化反应催化了环苄醚的氧化动力学拆分。实际的方法适用于范围广泛的1,3-二氢异苯并呋喃,其在α位置带有多种官能团和取代基,并具有非常有效的对映歧化作用。该策略的普遍性通过另一种五元环状苄基醚,2,3-二氢苯并呋喃和六元6H-苯并[c]苯二酚的有效氧化动力学拆分得到了进一步证明。进一步探索了否则难以获得的生物活性分子的直接后期氧化动力学拆分。
