obtained by the oxidation of l-cis-carvyl acetate with selenium dioxide. The hydrogenation of each 6,8(9)-p-menthadien-2,4-diol gave a different pair of p-menthane-2,4-diols, one pair being p-menthane-2,4-diols (III and IV) from trans-2,4-diol (I) and the other pair being p-menthane-2,4-diols (V and VI) from cis-2,4-diol (II). The absolute configurations of the p-menthane-2,4-diols (III, IV, V and VI) were
6,8(9)-p-Menthadien-trans-2,4-diol (I) 和 6,8(9)-p-menthadien-cis-2,4-diol (II) l-cis-carvyl醋酸盐与二氧化硒。每个 6,8(9)-p-menthadien-2,4-二醇的氢化得到一对不同的对薄荷烷-2,4-二醇,一对是对薄荷烷-2,4-二醇(III 和IV) 来自反式-2,4-二醇 (I),另一对是来自顺式-2,4-二醇 (II) 的对薄荷烷-2,4-二醇(V 和 VI)。对薄荷烷-2,4-二醇(III、IV、V 和 VI)的绝对构型基于化学证据、IR 和 NMR 数据以及氧化的棉花效应符号指定如下这些异构体的产物: III, (1S : 2R : 4S); IV,(红外:2R:4S);V, (1R : 2R : 4R) 和 VI, (1S : 2R : 4R)-p-薄荷烷-2,4-二醇。
