Base-catalyzed autoxidation of a triterpene ketone, friedelin, in the presence of potassium t-butoxide gave four products, and their structures and formation mechanism were investigated. The common intermediate to these compounds was suggested to be 4-hydroperoxyfriedelan-3-one, not friedelane-2,3-dione. 3-Oxafriedel-1-ene-2-carboxylic acid was a dehydration product of the main product, 2-hydroxy-
在叔丁醇钾的存在下碱催化三萜酮弗里德林自氧化得到四种产物,并研究了它们的结构和形成机制。这些化合物的常见中间体被认为是 4-hydroperoxyfriedelan-3-one,而不是 Friedelane-2,3-dione。3-Oxafriedel-1-ene-2-羧酸是主要产物2-羟基-3-oxafriedelane-2-羧酸的脱水产物。
