emerging bench-stable reagents for the generation of electron-rich oxycarbenes that are difficult to access with unstable diazo compounds. Herein, we report a siloxycarbene-mediated stereoselective synthesis of silyl enol ethers through visible-light-induced intermolecular reactions between acylsilanes and α,β-unsaturated ketones. Both the solvent and low temperature are important for the success of the
酰基硅烷是新兴的实验室稳定试剂,用于生成富电子的氧卡宾,而不稳定的重氮化合物难以获得这些氧卡宾。在此,我们报道了通过可见光诱导酰基硅烷和α,β-不饱和酮之间的分子间反应,硅氧卡宾介导的硅烯醇醚的立体选择性合成。溶剂和低温对于反应的成功都很重要。这种方法具有原子经济学、独特的立体控制和广泛的底物范围。该方法的合成潜力通过克级反应和各种下游转化(包括要求硅烯醇醚构型纯度的转化)得到证明。
