2-(3(4)-Hydroxy-4(3)-methoxyphenyl)-4,7-dimethyl-3,4,4a,5,8,8a-hexahydro-2H-chromene-4,8-diols were found recently to possess high analgesic activity and low acute toxicity. Stereoisomers of these compounds with high optical purity were synthesized from (+)- and (−)-α-pinenes for the first time in this work. The structure of (4S)-4b isomer was confirmed by the XRD data. Studies of analgesic activity
发现了2-(3(4)-羟基-4(3)-甲氧基苯基)-4,7-二甲基-3,4,4a,5,8,8a-六氢-2 H-色烯-4,8-二醇最近具有高止痛活性和低急性毒性。在这项工作中,首次从(+)-和(-)-α-pine烯合成具有高光学纯度的这些化合物的立体异构体。通过XRD数据证实了(4S)-4b异构体的结构。对所得产物的镇痛活性的研究表明,邻位氧原子的绝对构型和顺式或反式排列均未在这些异构体的镇痛作用表现中发挥重要作用,而只有(4 S)-4b异构体,但没有(4R)-4b显示了镇痛作用。
