  Analgesic and antimicrobial studies of some 2,4-dichloro-5-fluorophenyl containing arylidenetriazolothiadiazines

  摘要：

  2,4-Dichloro-5-fluorophenyl containing 7-arylidenetriazolothiadiazines were obtained by the reaction of 4-amino-3-(2,4-dichloro-5-fluorophenyl)-5-mercapto-1,2,4-triazole with 2,3-dibromo-1,3-diarylpropan-1-ones, and also by the reaction of 4-amino-3-(2,4-dichloro-5-fluorophenyl)-5-mercapto-1,2,4-triazole with alpha-bromopropenones in the presence of a base. The structure of the 7-arylidenetriazolothiadiazines was confirmed by an alternative synthesis. A plausible mechanism for the formation of 7-arylidenetriazolothiadiazines is proposed. All newly synthesized compounds were screened for their analgesic and antimicrobial activities. Compounds bearing 4-chlorophenyl or 3,4-methylenedioxyphenyl moieties at position 7 of the arylidenetriazolothiadiazines showed excellent analgesic activity. Arylidenetriazolothiadiazines carrying a phenyl, 4-chlorophenyl, 4-methylphenyl, 3,4-dimethoxyphenyl, and 2,4-dichlorophenyl moieties at position 7 showed excellent antibacterial and antifungal activities.

  3-b]furan-4,9-diones has been developed by N-iodosuccinimide (NIS)-induced enone difunctionalization with 2-hydroxy-1,4-naphthoquinones. This reaction involved sequential Michael addition, intramolecular oxidative cyclization and dehydrogenative aromatization to form new C–C and C–O bonds at the α and β positions of the enones. Various enones survived under the reaction conditions and the corresponding products

  A nucleophilic substitution of allylic alcohols with carbon (arene, heteroarene, allyltrimethylsilane, and 1,3-dicarbonyl compound), sulfur (thiol), oxygen (alcohol), and nitrogen (sulfonamide) nucleophiles has been demonstrated using an in house developed [Ir(COD)(SnCl3)l(μ-Cl)]2 heterobimetallic catalyst in 1,2-dichloroethane to afford the corresponding allylic products in moderate to excellent yields

  functional building blocks. Direct N-allylation of pyrazole and its derivatives as an atom economic strategy to provide allylic amines has been achieved only using commercial Bu4NHSO4 as the metal-free catalyst and water as the solvent without any additives. 11–93% isolated yields were obtained for the N-allylation of pyrazole and its derivatives with allylic alcohols. Bu4NHSO4 could be reused for

  烯丙胺是有价值的功能性构件。吡唑及其衍生物的直接N-烯丙基化作为提供烯丙胺的原子经济策略已经实现，仅使用商业 Bu 4 NHSO 4作为无金属催化剂和水作为溶剂而没有任何添加剂。吡唑及其衍生物与烯丙醇的N-烯丙基化获得了 11-93% 的分离产率。布4 NHSO 4可通过简单提取重复使用六次，几乎不损失催化活性，也适用于克级规模生产。烯丙醚和吡唑没有发生反应以得到所需产物表明烯丙醚不是该途径中的活性中间体。密度泛函理论 (DFT) 计算表明，底物、溶剂和催化剂之间存在氢键作用，尤其是烯丙醇和 H 2 O之间形成的氢键作用。不同质子溶剂中的对照实验进一步证明了烯丙醇和水的分子间氢键.

  A convenient additive-free synthesis of dihydro-4H-1,2-oxazines via a Cloke-Wilson-type ring expansion of the aryl-substituted cyclopropane carbaldehydes with the hydroxylamine salt is introduced. Comparatively less active cyclopropyl ketones also follow a similar protocol if supplemented by catalytic p-toluene sulfonic acid monohydrate. The transformation is performed in an open-to-air flask as it

  通过芳基取代的环丙烷甲醛与羟胺盐的Cloke-Wilson型扩环，方便地合成了二氢-4H-1,2-恶嗪。如果由催化对甲苯磺酸一水合物补充，则活性相对较低的环丙基酮也遵循类似的方案。由于它对空气/水分的敏感性可以忽略不计，因此在露天烧瓶中进行转化。当二氢-4H-1,2-恶嗪与环丙烷二酯进行环加成反应时，可以很容易地配制出有价值的六氢-2H-吡咯并[1,2-b] [1,2]恶嗪衍生物。这种两步策略的级联一锅法变体可提供最终产品相当的总产量。
