Gibberellane, Gibberellins, Isopimarane, Diterpenes. The natural isopimarenes 2–5, isolated from Velloziaceae species, with known absolute stereochemistry, were submitted to chemical transformations and afforded the tetracyclic lactones 10 and 11 with the gibberellane skeleton of the normal series. The 15-oxa-gibberellanes obtained are enantiomeric analogs of the natural gibberellins and this represents
赤霉素,赤霉素,异匹烷,二萜。从已知的绝对立体化学中分离出的黄柏科物种中的天然异海松烯2-5,经过化学转化,得到具有正常系列赤霉素骨架的四环内酯10和11。获得的15-氧杂赤霉素是天然赤霉素的对映体类似物,这代表了这类化合物的首次合成。
