    摘要:
    Enantiopure (P)4- 和 (M)4-配置的aleno-炔笼 (AAC) 受体为立体化学复杂的氯硫脂 danicalipin A 的小分子片段的络合和结构解析提供了高度明确的内部结构。 溶液 (NMR),固体状态(X 射线)和对形成的主客体复合物的理论研究提供了对 danicalipin A 氯醇核心的 14 种非手性和手性衍生物的构象偏好的洞察,在封闭的、主要是疏水的环境中,扩展了先前报道的极性溶剂研究. 客体的保守结合模式允许破译官能团置换对吉布斯结合能 ΔG 的影响。揭示了构象能量对结合亲和力的强烈贡献,这解释了为什么客体较大的非极性域的密集堆积不一定会导致更高的关联。手性客体的对映选择性结合,非对映异构复合物之间的能量差异ΔΔG293 K高达0.7 kcal mol-1,可以通过氢键和卤素键以及分散相互作用来解释。量热研究 (ITC) 表明,一种对映异构体的更强结合伴随着焓

    A number of allylic alcohols bearing a trifluoromethyl group at the α- or γ-position, and α-trifluoromethylated γ-enols and -ynols were prepared by the reaction of trifluoroacetaldehyde with a variety of organometallic compounds. Most of the Reformatsky- or Grignard-type reactions required promotion by ultrasonic irradiation.

  • Synthesis, Structure-Activity Relationships, and Pharmacological Evaluation of a Series of Fluorinated 3-Benzyl-5-Indolecarboxamides: Identification of 4-[[5-[((2R)-2-Methyl-4,4,4-trifluorobutyl)carbamoyl]-1-methylindol-3-yl]methyl]-3methoxy-N-[(2-methylphenyl)sulfonyl]benzamide, a Potent, Orally Active Antagonist of Leukotrienes D4 and E4

    日期:1994.4
    The continued exploration of a series of 3-(arylmethyl)-1H-indole-5-carboxamides by the introduction of fluorinated amide substituents has resulted in the discovery of 4-[[5-[((2R)-2-methyl-4,4,4-trifluorobutyl)carbamoyl]-1-methylindol-3-yl]methyl]-3-methoxy-N-[(2-methylphenyl)sulfonyl]benzamide (38p, ZENECA ZD 3523),which has been chosen for clinical evaluation. This compound exhibited a K-i of 0.42 nM for displacement of [H-3]LTD(4) on guinea pig lung membranes, a pK(B) Of 10.13 +/- 0.14 versus LTE(4) on guinea pig trachea, and an oral ED(50) Of 1.14 mu mol/kg opposite LTD(4)-induced bronchoconstriction in guinea pigs. The R enantiomer was found to be modestly more potent than the S enantiomer 38o. Modification of the amide substituent to afford achiral compounds was unsuccessful in achieving comparable levels of activity. Profiling of 38p opposite a variety of functional assays has demonstrated the selectivity of this compound as a leukotriene receptor antagonist. The enantioselective synthesis of 38p, which employed a diastereoselective alkylation of (4R,5S)-3-(1-oxo-4,4,4-trifluorobutyl)-4-methyl-5-phenyl-2-oxazolidinone (27) as the key step to establish the chirality of the amide substituent, provided an efficient route for generating 38p in >99% enantiomeric purity.
