series of variously functionalized alkylbenzylketones. A large range of functional groups were well tolerated on the ortho‐, meta‐ and para‐positions by this mild process regardless of their electronic effects, demonstrating the general character of the present methodology. The trimethylsilylchloride/sodium iodide reducing process was also successfully applied to reduce α‐ketoacid and α‐ketoester substrates
据报道,三甲基甲硅烷基氯化物/碘化钠可有效地对芳基烷基1,2-二酮进行区域选择性脱氧。在所有情况下,脱氧都在室温下在二氯甲烷中芳族环附近的羰基基团(Cα= O)上以高收率进行,从而提供了一系列各种官能化的烷基苄基酮。不管它们的电子作用如何,通过这种温和的过程,对邻位,间位和对位的各种官能团都具有良好的耐受性,这证明了本方法学的一般特征。三甲基甲硅烷基氯/碘化钠还原工艺也成功地用于还原α-酮酸和α-酮酸酯底物。
