The conformational analysis of (+)-p-menthane-3,4-diol, which had been obtained by the hydroxylation of (+)-p-menth-3-ene with performic acid in the presence of water, has been performed mainly by means of infrared spectra. It has been shown that the two hydroxyl groups at the C3- and C4-positions take a diaxial conformation, that they are, accordingly, trans to each other, and that the methyl group
(+)-p-menthane-3,4-diol 的构象分析是由 (+)-p-menth-3-ene 与
过甲酸在
水存在下羟基化得到的。通过红外光谱。已经表明,C3-和C4-位的两个羟基采取双轴构象,因此它们彼此反式,并且甲基可能保持赤道取向。还发现
