The oxidation of 3β-hydroxylanostan-7-one hydrazone with lead tetra-acetate gave, after acetylation, 3β-acetoxylanost-7-ene and, as major product, 3β,7α-diacetoxylanostane. The corresponding oxidation of 3β-hydroxylanost-24-en-7-one hydrazone gave 3β-hydroxylanosta-7,24-diene and, as main product, 3β-hydroxy-7α-acetoxylanost-24-ene. The corresponding reactions of benzophenone hydrazone, dicyclohexyl
乙酰化后,用四乙酸铅氧化3β-羟基羊毛甾烷-7-,生成3β-乙酰氧基羊毛脂-7-烯,并作为主要产物3β,7α-二乙酰氧基羊毛甾烷。3β-羟基羊毛脂-24-en-7-one的相应氧化得到3β-羟基羊毛脂-7,24-二烯和3β-羟基-7α-乙酰氧基羊毛脂-24-烯作为主要产物。还研究了二苯甲酮,、二环己基酮和樟脑的相应反应,以研究氧化机理。
