its methyl ester (2) were investigated under various storage conditions to provide an indication of their preferred oxidation mechanisms and to investigate the most susceptible positions for modification in the abietane skeleton. Six known compounds, methyl 7alpha,13beta-dihydroxyabiet-8(14)-enoate (4a), methyl 7alpha,13alpha-dihydroxyabiet-8(14)-enoate (4b), methyl 12-oxoabietate (6), methyl 7-oxodehydroabietate
在各种储存条件下研究了松果酸(1)及其甲酯(2),以提供它们优选的氧化机理的指示,并研究在松果烷骨架中修饰的最敏感位置。六种已知化合物,7alpha,13beta-dihydroxyabiet-8(14)-enoate甲基(4a),7alpha,13alpha-dihydroxyabiet-8(14)-enoate甲基(4b),12-oxoabietate甲基(6),7-oxodehydroabietate甲基(7)鉴定出7α-羟基脱氢松香酸甲酯(8)和13,14-seco-13,14-dioxoabiet-7(8)-烯酸(11)。化合物7和8被认为是有效的过敏原。此外,还分离出六种新的氧化产物,分别是13β-乙氧基-7α-羟基枞8(14)-烯酸酯(3a),13α-乙氧基-7α-羟基枞8(14)-烯酸酯(3b),甲基7alpha-hydroperoxy-13alpha-hydroxya
