oxidative acylation of α,α‐diarylallylic alcohols with simple aromatic aldehydes for the synthesis of 1,2,4‐triphenylbutane‐1,4‐diones is presented. In the presence of TBPB (tert‐butyl peroxybenzoate), desired products were obtained in good to excellent yields for 28 examples. This protocol features high regioselectivity, wide functional group tolerance and atom economy.
提出了无金属介导的α,α-二芳基烯丙基醇与简单的芳香醛的氧化酰化反应,用于合成1,2,4-三苯基丁烷-1,4-二酮。在TBPB(过氧苯甲酸叔丁酯)存在下,以28个实例获得了所需产品,收率良好或优异。该协议具有高区域选择性,宽泛的官能团耐受性和原子经济性的特点。
