6-Methylellipticine (6) undergoes acylation at the C(9)-position, under Friedel Crafts reaction conditions. The C(9)-formyl compound (8) rearranges to the corresponding hydroxy derivative (9) upon treatment with hydrogen peroxide, in methanol, in the presence of sulphuric acid. The two steps provide a convenient procedure for the specific C(9)-hydroxylation of the ellipticine template.

玫瑰树碱(6)在Friedel Crafts反应条件下在C(9)位置进行酰化。在
甲醇中,在
硫酸存在下,用
过氧化氢处理后,C(9)-甲酰基化合物(8)重排为相应的羟基衍
生物(9)。这两个步骤为
