keto-diester, C(20)H(24)O(6), a potential intermediate in the synthesis of bioactive podocarpic acid, the outer cyclohexane ring (in a chair conformation) is cis fused to the central cyclohexanone ring (in a half-chair conformation). The conformational analysis of the compound, investigated by semi-empirical quantum mechanical AM1 calculations, shows a good agreement with the X-ray structure, except for the
在标题三环酮二酯C(20)H(24)O(6)中,这是生物活性罗汉果酸合成的潜在中间体,外环己烷环(呈椅子构型)顺式稠合至中央环己酮环(半椅式)。通过半经验量子力学AM1计算研究的化合物的构象分析显示,除了甲基,甲氧基苯基和甲氧基羰基取代基的取向外,其与X射线结构的一致性很好。
