| Abstract: | The oxidation of 3β-hydroxy-olean-12-ene with monooxygen donors catalyzed by 5, 10,15,20- tetraarylporphyrinatoiron(III) chlorides in dichloromethane gives 3β, 11α-dihydroxy-olean-12-ene, 3-oxo-olean-12-ene, 3,11-dioxo-olean-12-ene and 3β-hydroxy-olean-9(11), 12-diene whereas the oxidation of 3β -acetoxy-olean-12-ene under similar conditions gives 11 (-hydroxy-3β -acetoxy-olean-12-ene, 11-oxo-3β -acetoxy-olean-12-ene and 3β-acetoxy-olean- 9(11),12-diene in moderate yields. |
