摘要：

We have found that, analogous to the known behavior of longifolene, sativene (5) is isomerized by treatment with Cu(OAc)2 in refluxmg acetic acid to an equilibrium mixture of isomeric sesquiterpenes consisting of recovered sativene (7%), cyclosativene (7, 32%), and isosativene (8, 61%). We have also completed a total synthesis of copacamphene (12) and have found that it too is isomemed to this...
