  • Cannabinoid studies. IV. Stereoselective and regiospecific syntheses of (±)-Δ9-trans- and (±)-Δ9-cis-6a, 10a-Tetrahydrocannabinol
    作者:M Moore、RW Rickards、H R°nneberg
    DOI:10.1071/ch9842339

    Efficient syntheses of the title compounds are achieved through the intermediate alcohols (13) and (15), prepared by reaction of citral (10) with the lithiated olivetol dimethyl and di(methoxymethy1) ethers (4) and (6). Reaction of the alcohol (13) with boron tribromide yields (�)-∆9-trans-6a,10a- tetrahydrocannabinol (1) after regiospecific dehydrobromination of its hydrogen bromide adduct, whilst treatment of the alcohol (15) with trimethylsilyl bromide affords (�)-∆9-cis-6a,10a-tetra-hydrocannabinol(11). The complementary stereoselectivity of these reactions may provide insight into the nature of cannabinoid cyclization processes.

  • Synthesis of Tetrahydrocannabinols Based on an Indirect 1,4-Addition Strategy
    作者:Anthony D. William、Yuichi Kobayashi
    DOI:10.1021/jo020457m
    日期:2002.12.1
    requires 1,4-addition of bulky cuprates to cyclohexenones and subsequent reaction with electrophiles. However, the enolates generated by BF(3).OEt(2)-assistance suffer from lack of nucleophilicity. To circumvent this problem, we developed an indirect method consisting of the following three steps: (1) iodination of the cyclohexenones at the alpha position; (2) BF(3).OEt(2)-assisted 1,4-addition of cuprates
    提出的用于制备标题化合物的合成方法需要将1,4-大体积的铜酸盐加到环己酮中,随后与亲电试剂反应。但是,由BF(3).OEt(2)-助剂生成的烯醇盐缺乏亲核性。为了解决这个问题,我们开发了一种间接方法,该方法包括以下三个步骤:(1)环己酮在α位置的碘化;(2)BF(3).OEt(2)辅助1,4加成铜酸盐(Ar(2)Cu(CN)Li(2),Ar =芳基),然后用水淬灭烯醇化物;(3)如此形成的α-碘-β-芳基-环己酮与EtMgBr反应生成烯醇镁。以此方式产生的烯醇化物显示出对ClP(O)(OEt)(2)的高反应性,以提供烯醇式磷酸酯。前述程序也适用于旋光性Delta(9)-四氢大麻酚的合成。另外,也以类似的方式合成了后一种化合物的萘类似物。
  • A Method To Accomplish a 1,4-Addition Reaction of Bulky Nucleophiles to Enones and Subsequent Formation of Reactive Enolates
    作者:Anthony D. William、Yuichi Kobayashi

    日期:2001.6.1
    [reaction: see text] BF(3)-promoted 1,4-addition of bulky aryl groups to alpha-iodo enones, prepared from the parent enones, afforded beta-aryl-alpha-iodo ketones. Subsequent reaction with EtMgBr furnished the magnesium enolates, which upon reactions with ClP(O)(OEt)(2) and aldehydes gave enol phosphates and aldols, respectively. This method was applied successfully to a synthesis of Delta(1)-tran
    [反应:见正文]由母体烯酮制备的BF(3)促进大体积芳基与α-碘烯酮的1,4-加成反应,得到β-芳基-α-碘酮。随后与EtMgBr的反应提供了烯醇镁,其与ClP(O)(OEt)(2)和醛反应后分别得到了烯醇磷酸酯和羟醛。该方法已成功应用于Delta(1)-反式-四氢大麻酚的合成。
  • Activation of Marginally Reactive Boron Enolates by MeLi for the Formation of Enol Phosphates and Synthesis of the Δ<sup>9</sup>-THC Intermediate
    作者:Hiroki Kawada、Atsushi Ikoma、Narihito Ogawa、Yuichi Kobayashi

    enones was followed by the reaction with ClP(O)(OEt)2 to afford the corresponding enol phosphates in moderate to good yields. The scope of this method was examined with sterically hindered or electronically biased enones and/or reagents. This activation of boron enolates was successfully applied to the synthesis of the methyl ether of Δ9-tetrahydrocannabinol.
    将MeLi添加到BF 3 ·OEt 2活化的烯酮中1,4-加成Ar 2 Cu(CN)Li 2产生的烯醇硼中,然后与ClP(O)(OEt)2反应,得到相应的烯醇磷酸酯,产率中等至良好。用空间受阻或电子偏压的烯酮和/或试剂检查了该方法的范围。硼烯醇化物的这种激活成功地应用于Δ的甲基醚的合成9四氢大麻酚。

    The present invention relates to a tetrahydrocannabinol (THC) type cannabinoid compound for use as a medicament. The THC-type cannabinoid is an enantiomer of the (-)-trans- tetrahydrocannabinol which is a naturally occurring cannabinoid that can be found in cannabis plant strains which have been bred to yield THC as the dominant cannabinoid. The particular enantiomer (+)-cis tetrahydrocannabinol has been found to have properties which are different from the naturally occurring (-)-trans-THC. The cannabinoid (+)-cis-THC has been found to occur in low concentrations in particular cannabis plant strains which have been bred to produce cannabidiol (CBD) as the dominant cannabinoid. Furthermore, the cannabinoid can be produced by synthetic means.
    本发明涉及一种四氢大麻酚(THC)型大麻素化合物,用作药物。THC型大麻素是(-)-反式四氢大麻酚的对映体,它是一种天然存在的大麻素,可在经过育种以产生THC为主要大麻素的大麻植物品种中找到。特定的对映体(+)-顺式四氢大麻酚已被发现具有与天然存在的(-)-反式THC不同的特性。大麻素(+)-顺式THC已被发现以低浓度存在于特定的大麻植物品种中,这些品种经过育种以产生大麻二酚(CBD)作为主要大麻素。此外,这种大麻素可以通过合成方式生产。
