organocatalytic synthetic procedure for the synthesis of hydroxylactones from alkenoic acids is described. The reaction includes the activation of H2O2 by an organocatalyst (2,2,2‐trifluoromethylacetophenone), the oxidation of an olefinic group to the corresponding epoxide, and intramolecular lactonization to afford a variety of substituted γ‐ or δ‐lactones with multiple substitution patterns in good
沿着现代可持续氧化的路线,描述了一种绿色和温和的有机催化合成方法,用于从链烯酸合成羟基内酯。反应包括有机催化剂(2,2,2-三氟甲基苯乙酮)活化H 2 O 2,烯基氧化为相应的环氧化物以及分子内酯化以提供各种取代的γ-或δ-内酯多种替代模式,高到高产量。如果转化率是定量的,则在简单萃取后就可以得到高纯度的产物。试图使过程不对称的尝试取得了有限的成功。
