Abstract The structure of the diterpene nimbinone 1b has been confirmed by syntheses via a cascade cyclisation and also from podocarpic acid by two separate series of transformations. Synthesis of structure 3b from dehydroabietic acid shows that this does not exhibit the properties described for nimbosodione.
摘要 通过级联环化合成和罗汉果酸通过两个独立的转化系列已经证实了二萜茚酮 1b 的结构。由脱氢枞酸合成结构 3b 表明,这不表现出对 Nimbosodione 所述的性质。
