Conjugated esters from (+)-isopinocamphone, with a terpenic skeleton which is easily epimerizable may theoretically exist as four diastereomers (2R,4E; 2R,4Z; 2S,4E; 2S,4Z). X-Ray analysis shows that the reaction leads to a single isomer, namely an isopinocamphone derivative (2S,4E).
由(+)-异松苓酮生成的大环酯,其萜类骨架易于差向异构化,理论上有四种立体异构体(2R,4E;2R,4Z;2S,4E;2S,4Z)。X射线分析表明,该反应生成单一对映体,即异松苓酮衍生物(2S,4E)。
