The configurations of 4βH-thujan-2-one (isodihydroumbellulone) and the two 4βH-thujan-2-ols (neoiso- and iso-dihydroumbellulols) have been determined by 1H and 13C n.m.r. spectroscopy. Based on these data, the reduction of the title compounds by metal hydrides and alkoxides has been shown to be consistent with control of stereoselectivity by the reactant conformation.
4β的配置ħ -thujan -2-酮(isodihydroumbellulone)和两个4β ħ -thujan -2-醇(neoiso-和异dihydroumbellulols)已通过测定1 H和13 C NMR光谱。基于这些数据,已经证明金属氢化物和醇盐对标题化合物的还原与通过反应物构象控制立体选择性是一致的。
