  • [EN] CONFORMATIONALLY CONSTRAINED, FULLY SYNTHETIC MACROCYCLIC COMPOUNDS<br/>[FR] COMPOSÉS MACROCYCLIQUES ENTIÈREMENT SYNTHÉTIQUES, À CONFORMATION CONTRAINTE

    Conformationally restricted, spatially defined 12-30 membered macrocyclic ring systems of type (I) are constituted by three distinct building blocks: an aromatic template a, a conformation modulator b and a spacer moiety c as detailed in the description and the claims. Macrocycles of type (I) are readily manufactured by parallel synthesis or combinatorial chemistry. They are designed to interact with specific biological targets. In particular, they show agonistic or antagonistic activity on the motilin receptor (MR receptor), on the serotonin receptor of subtype 5-HT2B (5-HT2B receptor), and on the prostaglandin F2 • receptor (FP receptor). They are thus potentially useful for the treatment of hypomotility disorders of the gastrointestinal tract such as diabetic gastroparesis and constipation type irritable bowl syndrome; of CNS related diseases like migraine, schizophrenia, psychosis or depression; of ocular hypertension such as associated with glaucoma and preterm labour.
    构象受限、空间定义的12-30元大环环系统(I型)由三个不同的构建模块组成:芳香模板a、构象调节剂b和间隔基团c,详细描述在说明书和专利要求中。I型大环可通过并行合成或组合化学方法轻松制备。它们设计用于与特定生物靶点相互作用。特别是,它们在胃动素受体(MR受体)、5-羟色胺受体亚型5-HT2B(5-HT2B受体)和前列腺素F2•受体(FP受体)上显示激动或拮抗活性。因此,它们潜在用于治疗胃肠道低动力障碍,如糖尿病性胃轻瘫和便秘型肠易激综合征;中枢神经系统相关疾病,如偏头痛、精神分裂症、精神病或抑郁症;眼压增高,如青光眼和早产。

    Alkynes were successfully converted into α,β-acetylenic carbonyl compounds through radical-catalyzed aerobic oxidation using N-hydroxyphthalimide (NHPI) combined with a transion metal under mild conditions.

  • An unprecedented highly efficient solvent-free oxidation of alkynes to α,β-acetylenic ketones with tert-butyl hydroperoxide catalyzed by water-soluble copper complex
    作者:Abdelaziz Nait Ajjou、Gabriel Ferguson
    DOI:10.1016/j.tetlet.2006.03.140
    日期:2006.5
    catalytic system composed of CuCl2 and 2,2′-biquinoline-4,4′-dicarboxylic acid dipotassium salt (BQC) was found to be highly efficient for the selective α-oxidation of internal alkynes to the corresponding α,β-acetylenic ketones, with aqueous tert-butyl hydroperoxide under mild conditions. For the first time, full conversions of alkynes were reached with excellent selectivities, and propargylic tert-butylperoxy

    DOI:10.1021/ja808673n
    日期:2008.12.24
    Allyl-aryl coupling between allylic acetates and arylboronic acids took place in the presence of catalytic amounts of Pd(OAc)(2), 1,10-phenanthroline, and AgSbF(6) with high gamma-selectivity and E/Z-selectivity. The reaction of an optically active allylic acetates with an alpha-stereogenic center proceeded with excellent alpha-to-gamma chirality transfer with syn-selectivity and gave the corresponding

    A mild propargylic oxidation of alkynes is reported using a diacetoxyiodobenzene/tert-butyl hydroperoxide (DIB/TBHP) protocol. The reactions proceed smoothly at 0 °C and a number of α,β-unsaturated alkynoic ketones are obtained.
