    吗啡-蒂巴因组中的新型镇痛剂和分子重排。三、6,14-endo-ethenotetrahydrooripavine 系列的醇和 N-烯丙基去甲吗啡和-去甲可待因的衍生类似物
    摘要:
    通式结构 IV 和 V 的仲醇和叔醇是通过本系列第 I1 部分中描述的相应碱 I 和 I1 的脱甲基化制备的。如此获得的酚类是具有极高效力的镇痛剂,其强度是吗啡的 12,000 倍,这是史无前例的。该系列和更早系列的碱已通过 N-氰基化合物和新的 N,N'-亚甲基双化合物 XI11 转化为通式结构 XI 和 XI1 的 N-烯丙基诺吗啡和 N-烯丙基诺可待因的类似物。 I和I1与偶氮二羧酸甲酯。XI1 系列的某些碱基是具有前所未有效力的吗啡拮抗剂,高达 N-烯丙基吗啡的 150 倍。在之前的论文中,报道了通式结构 I 和 I1 的两个系列 I 可待因衍生物的制备,其中许多成员作为镇痛剂的活性比以前在吗啡-蒂巴因组中制备的任何碱都要高得多。由于可待因衍生物去甲基化为相应的吗啡衍生物几乎总是导致镇痛活性显着增加,因此结构 I 和 I1 的大部分醇都转化为相关的酚类。由于醇非常容易进行酸催化重排

    摘要:
    蒂巴因(3)在日光下的光氧化作用产生两种主要产物:加氢二苯并呋喃10(主要)和苯并呋喃11(次要)。如果使用汞灯代替太阳灯,则后一种化合物将占主导地位。10的形成经由过氧过氧化物中间体进行,该中间体在氮原子上进行氧化。通过质子化或季铵化保护氮防止了其氧化,因此在酸性介质中对3进行光氧化构成了制备14-羟基可待因酮35的一锅法。蒂巴因铵盐31的光氧化使得能够以高收率分离出蒂巴因铵盐31。相应地对应于蒂巴因内过氧化物32。加氢二苯并呋喃10的酮基,醛基和烯基的选择性保护和还原使得可以制备几种二醇和酮醇衍生物。

  • N-Demethylation of N-methyl alkaloids with ferrocene
    作者:Gaik B. Kok、Peter J. Scammells
    DOI:10.1016/j.bmcl.2010.06.031
    日期:2010.8
    ferrocene has been found to be a convenient and efficient catalyst for the N-demethylation of a number of N-methyl alkaloids such as opiates and tropanes. By judicious choice of solvent, good yields have been obtained for dextromethorphan, codeine methyl ether, and thebaine. The current methodology is also successful for the N-demethylation of morphine, oripavine, and tropane alkaloids, producing the corresponding

  • New nepenthone and thevinone derivatives
    作者:János Marton、Csaba Simon、Sándor Hosztafi、Zoltán Szabó、Árpád Márki、Anna Borsodi、Sándor Makleit

    The diastereoselective reaction of thevinone (2a) and nepenthone (2c) and their dihydro derivatives (2b and d) with Grignard reagents afforded new N-substituted (20S)- and (20R)-phenyl-6,14-ethenomorphinan derivatives (6a-y). The Grignard reaction of the N-substituted-N-demethyl derivatives 4a-f and 4m-r with methylmagnesium iodide resulted in the (20R)-phenyl tertiary alcohols 5a-f and 5m-r, respectively
    酮(2a)和醌(2c)及其二氢衍生物(2b和d)与格利雅试剂的非对映选择性反应提供了新的N-取代的(20S)-和(20R)-苯基-6,14-乙炔吗啡喃衍生物(6a- y)。N-取代-N-去甲基衍生物4a-f和4m-r与甲基碘化镁的格氏反应分别产生了(20R)-苯基叔醇5a-f和5m-r,但是4g-1的转化率和用苯基溴化镁的N-取代的二氢噻酮生物得到的(20S)-苯基衍生物分别为5g-1和5s-y。通过化合物5的3-O-去甲基化制备N-环丙基甲基-,N-β-苯乙基和N-丙基衍生物。用于合成N-烯丙基,N-二甲基烯丙基和N-炔丙基。化合物2a-d与相应的格氏试剂反应,用溴化氰处理产物,得到酰胺8a-d。后面这些化合物被转化为10a,b,d,其烷基化导致目标衍生物6d-f,jl,pr和wy。这些物质的生化研究表明,与δ-阿片受体的亲和力很高,但选择性很低。在两种情况下(6c和11d),观察到了阿片类受体的特异性。
  • Polonovski-Type N-Demethylation of N-Methyl Alkaloids Using Substituted Ferrocene Redox Catalysts
    作者:Peter Scammells、Gaik Kok
    DOI:10.1055/s-0032-1316590
    日期:2012.8
    Various substituted ferrocenes have been trialed as catalysts in the nonclassical Polonovski reaction for N-demethylation of N-methyl alkaloids. Earlier studies suggest that conditions facilitating a higher ferrocenium ion concentration lead to superior outcomes. In this regard, the bifunctional ferrocene FcCH(2)CO(2)H, with electron donor and acceptor moieties in the same molecule, has been shown to be advantageous for use as a catalyst in the N-demethylation of a number of tertiary N-methylamines such as codeine, thebaine, and oripavine. These substrates are readily N-demethylated under mild conditions, employing sub-stoichiometric amounts of the substituted ferrocene at ambient temperature. These reactions are equally efficient in air and may also be carried out in one pot.
  • Electrophilic .alpha.-methylene-.gamma.-lactone and isothiocyanate opioid ligands related to etorphine
    作者:Peter Klein、Wendel L. Nelson、Yi He Yao、Eric J. Simon
    DOI:10.1021/jm00170a038
    日期:1990.8
    Isothiocyanate and alpha-methylene-gamma-lactone analogues of 6,14-endo-ethenotetrahydrothebaine and -oripavine were prepared with the electrophilic groups being located at C-19 in the C-7 alpha-side chain. Isothiocyanates were prepared in the N-Me and N-CPM (N-cyclopropylmethyl) series, both as the phenols and 3-O-methyl ethers from the diastereomeric amines formed from reductive amination of thevinone (2) and N-(cyclopropylmethyl)northevinone (13). Although addition of the organozinc reagent from methyl alpha-bromomethacrylate to 25 failed, addition to 3-O-protected aldehydes 27 and 35 produced, after subsequent deprotection, alpha-methylene-gamma-lactones 29 and 37, respectively. In the opioid receptor displacement assays against [3H]bremazocine as the radiolabeled ligand, the phenolic compounds were most potent with N-CPM isothiocyanates 20 and 21 showing IC50s of 0.32 and 0.76 nM, respectively, and N-CPM alpha-methylene-gamma-lactone 37 having an IC50 = 1.0 nM. Compound 37 showed irreversible effects in the binding assay which were mu-selective, as demonstrated by analogous experiments using [3H]DAGO, and naloxone was found to protect against the irreversible effects. This observation suggests that a receptor-bound nucleophile is located at a position where it can readily reach the alpha-methylene group of lactone 37.
  • Photooxidation of thebaine. A route to 14-hydroxymorphinones and hydrodibenzofuran analogs of methadone
    作者:Dolores López、Emilio Quiñoá、Ricardo Riguera
    DOI:10.1016/s0040-4039(00)77290-x
    日期:1994.8
    The photooxidation of thebaine (1) produces a highly functionalized hydrodibenzofuran 2 via formation of the endoperoxide and a tert-amine radical cation. Photooxidation of the quaternary ammonium salt of thebaine 6, allows the isolation of the endoperoxide 7. Photooxidation of thebaine 1 in acidic medium (TFA), yields 14-hydroxycodeinone salt 3 via the corresponding endoperoxide.
