o- and p-cimen-9-ols in the presence of isopropyl alcohol selectively afforded the corresponding 1,4-dihydro derivatives. Under analogous conditions, o-cimen-7-ol was converted into a mixture of unsaturated hydrocarbons. The reduction with lithium in ethylenediamine in the absence of isopropyl alcohol in all cases gave mixtures of menthene alcohols.
合成了邻-和对-薄荷烷系列(o -cimen-7-ol和o-和p -cimen-9-ols)萜烯醇的前体,并研究了乙二胺中锂的还原反应。的还原ö -和p在异丙醇的存在下-cimen -9-醇选择性地得到相应的1,4-二氢衍生物。在类似条件下,邻-cimen-7-ol被转化为不饱和烃的混合物。在所有情况下,在不存在异丙醇的情况下,在乙二胺中用锂进行还原,得到了薄荷醇的混合物。
