(−)-Pulo'upone () was synthesized via an asymmetric, bornane-10,2-sultam- directed, intramolecular Diels- Alder reaction ( → ) and a 2-pyridylcuprate/allylacetate coupling ( → ). The (6'R, 9'S, 13'R, 14'R)- configuration of (−)- follows from an X-ray diffraction analysis of the cycloaddition product .
(-)-Pulo'upone()是通过不对称的,冰片烷,10,2-阿曼二酰胺导向的分子内Diels-Alder反应(→ )和2-吡啶基铜酸酯/烯丙基乙酸酯偶联(→ )合成的。(-)-的(6'R,9'S,13'R,14'R)-构型来自环加成产物的X射线衍射分析。
