Oxidation of α-amyrin acetate (3), β-amyrin acetate (1), ursolic acid acetate (5), hederagenin diacetate (7) and brahmic acid triacetate (9) by aqueous chromic trioxide in the presence of cetyltrimethylammonium bromide as phase-transfer catalyst in CCl4 furnishes the 11-oxo derivatives in more than 80percent yield.
