Persistent radical meets enolates: Catecholboron ketone enolates are oxidized efficiently under mild conditions by treatment with the persistent TEMPO radical. Catecholboron enolates are readily prepared by 1,4‐reduction of α,β‐unsaturated ketones or by transmetalation of silyl enol ethers and zinc enolates with chlorocatecholboranes. Enolate formation and oxidation can be performed as a one‐pot process
持久性自由基遇上烯醇化物:儿茶酚硼酮烯醇化物在温和条件下通过持久性TEMPO自由基进行有效氧化。邻苯二酚烯醇盐很容易通过α,β-不饱和酮的1,4-还原或通过氯代邻苯二硼烷对甲硅烷基烯醇醚和烯醇锌的金属转移而制备。烯醇盐的形成和氧化可以作为一锅法进行,具有很高的区域选择性和立体选择性。
