  Synthesis and anticonvulsant activity of new 6-methyl-1-substituted-4,6-diazaspiro[2.4]heptane-5,7-diones

  摘要：

  In the present study on the development of new anticonvulsants, twenty new 6-methyl-1-substituted-4,6-diazaspiro[2.4]heptane-5,7-diones were synthesized and tested for anticonvulsant activity using the maximal electroshock (MES) and subcutaneous pentylenetetrazole (scPTZ) screens. Their neurotoxicity was determined by the rotorod test. In this series, all of the alkyl- and aryl-substituted 5,5-cyclo-propanespirohydantoins showed more or less protection against MES and/or scPTZ models. The most active of the series was 6-methyl-1-(4-(methylsulfonyl)phenyl)-4,6-diazaspiro[2.4]heptane-5,7-dione (6t), which showed a MES ED50 value of 12.5 mg/kg in mice. The median toxic dose (TD50) was 310 mg/kg, providing compound 6t with a protection index (PI = TD50/ED50) of 24.8 in the MES test which is better than phenytoin. (C) 2010 Elsevier Masson SAS.

  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。

  catalyzed ring opening reaction of Donor–Acceptor (D–A) cyclopropanes with alkyl hydroperoxides is reported to furnish various peroxycarbonyls and 1,3-haloperoxygenated compounds in good to excellent yields. This method adds another instance to scarcely reported noncyclilizing 1,3-bisfunctionalization of D–A cyclopropanes with two different functional groups and relies on the dual role of peroxide as nucleophile

  据报道，路易斯酸催化的施主-受主（DA）环丙烷与烷基氢过氧化物的开环反应可提供各种过氧羰基化合物和1,3-卤代过氧化合物，收率良好至极佳。这种方法增加了另一个实例，即很少报道具有两个不同官能团的D–A环丙烷的1,3-双官能团的非环化，并且依赖于过氧化物作为亲核试剂和氧化剂的双重作用，通过精心安排的反应顺序。获得的产物，包括α-杂取代的过氧化合物，适合于有用的合成加工。

  efficient method for the synthesis of nitrogen‐functionalized cyclopentane derivatives via [3+2] cycloaddition of enamines with donor‐acceptor cyclopropanes in the presence of catalytic amounts of various Lewis acids at room temperature has been developed; furthermore, the corresponding β‐amino acid was synthesized by monodecarboxylation and hydrogenolysis. An enantioenriched synthesis of nitrogen‐functionalized

  在室温下催化量的各种路易斯酸存在下，开发了一种简单有效的方法，可通过烯胺与供体-受体环丙烷的[3 + 2]环加成反应，合成氮官能化的环戊烷衍生物；此外，通过单脱羧和氢解合成了相应的β-氨基酸。通过外消旋给体-受体环丙烷的动态动力学不对称转化，对氮官能化的环戊烷衍生物进行了对映体富集合成，采用铜络合物[Cu（OTf）2 - L1 ]作为催化剂，对映体比例高达8：1。

  In this report, a facile synthesis of tetrahydropyridazines via a Lewis acid catalyzed annulation reaction of cyclopropane carbaldehydes and aryl hydrazines has been demonstrated. Moreover, the generated tetrahydropyridazine further participated in a cycloaddition reaction with donor–acceptor cyclopropanes to furnish hexahydropyrrolo[1,2-b]pyridazines. We also performed these two steps in one pot in

  在该报告中，已经证明了通过路易斯酸催化的环丙烷甲醛和芳基肼的环合反应可轻松合成四氢哒嗪。此外，生成的四氢哒嗪进一步与供体-受体环丙烷一起参与环加成反应，提供六氢吡咯并[1,2- b ]哒嗪。我们还在一个锅中以连续的方式执行了这两个步骤。另外，六氢吡咯并[1,2- b ]哒嗪的单脱羧反应得到了良好的收率。

  substituents present in both reacting partners produced different products. The C-attack gave functionalized cyclopentane derivatives while the O-attack furnished tetrahydrofuran derivatives via [3+2]-annulation reactions. Moreover, to increase the utility of our method, synthesized diasteriomeric cyclopentane derivatives were converted into synthetically useful cyclopentene and cyclopentanone analog.

  取代基和路易斯酸促进从环氧化物生成官能化烯醇化物。烯醇化物对供体-受体环丙烷的不同攻击，即 C-攻击或 O-攻击，取决于两个反应伙伴中存在的取代基，产生不同的产物。C-攻击产生官能化的环戊烷衍生物，而O-攻击通过[3+2]-环化反应提供四氢呋喃衍生物。此外，为了提高我们方法的实用性，合成的非对映环戊烷衍生物被转化为合成有用的环戊烯和环戊酮类似物。
