and efficient method for regioselective acylation of mangiferin catalyzed by lipase under ultrasound irradiation is reported. Compared with the conventional methods, its main advantages are shorter reaction time and higher yields. The optimum conditions were screened out. Under the optimal conditions (lipase: PCL, acyl donor: vinyl acetate; reaction solvent: DMSO, reaction temperature: 45°C, ultrasonic
报道了一种简单有效的超声辐射下脂肪酶催化芒果苷区域选择性酰化的方法。与常规方法相比,其主要优点是反应时间短,产率高。筛选出最佳条件。在最佳条件下(脂肪酶:PCL,酰基供体:乙酸乙烯酯;反应溶剂:DMSO,反应温度:45°C,超声功率:200 W;底物比例:酰基供体/芒果苷6/1,酶负载:6 mg / ml),区域选择性酰化产率高达84%。
