Dronabinol, the tetrahydrocannabinol compound which comprises the active constituent of marijuana and is pharmaceutically useful as an antiemetic, is prepared by a process involving reaction of cis-menth-1-ene-3,8-diol with olivetol to form 1,3-dihydroxy-2-[(1R,6R)-6-(2-hydroxyprop-2-yl)-3-methylcyclohex-2-en-1-yl]-5-pentylbenzene; and cyclizing the 1,3-dihydroxy-2-[(1R,6R)-6-(2-hydroxypropr-2-yl)-3-methylcyclohex-2-en-1-yl]-5-pentylbenzene so formed to obtain dronabinol. A novel synthesis of cis-menth-1-ene-3,8-diol is also provided.
Dronabinol是四氢大麻酚化合物,它是大麻的活性成分,并且在药学上用作止吐剂,该化合物的制备涉及使用顺-薄荷烯-3,8-二醇与橄榄酚反应,形成1,3-二羟基-2-[(1R,6R)-6-(2-羟基丙基)-3-甲基环己-2-烯-1-基]-5-戊基苯; 并将形成的1,3-二羟基-2-[(1R,6R)-6-(2-羟基丙基)-3-甲基环己-2-烯-1-基]-5-戊基苯环化以获得Dronabinol。此外还提供了一种新的合成顺-薄荷烯-3,8-二醇的方法。
