Abstract: The conditions of betulin and betulin diacetate oxidation with 35 % H2O2 into their epoxides were studied. In the two-phase water-organic medium the oxidation reactions are carried out at mild conditions: atmosphreric pressure and temperature 60-80 °C. The reaction of betulin diacetate oxidation was realized with high yield of epoxide (90 %) and degree of the conversion 98 % in the presence of soluble catalyst [CH3(n-C8H17)3N]{PO4[WO(O2)2]4}.
