通过关键中间体3-(2,4,6-三甲基)-2-oxo-1-oxaspiro [4.4] -decyl-3-en-4设计并合成了一系列含有草酰部分的新型螺环四酸衍生物-ol。通过1 H NMR和元素分析或高分辨率质谱(HRMS)鉴定目标化合物。生物测定的结果表明,大多数目标化合物对胭脂红蜘蛛幼虫和卵具有出色的杀螨活性。特别是二异丙基氨基草酰化合物7g和哌啶草酰化合物7h分别是市售Spiromesifen对红蜘蛛卵的活性的1.4倍和2.3倍。而且,大多数目标化合物对鳞翅目害虫表现出杀虫活性。有趣的是,含有烷基氨基取代的草酰部分的化合物在红蜘蛛幼虫和卵之间显示出明显的选择性,因为对7g和7h的红蜘蛛卵的活性是对红蜘蛛幼虫的25倍,而Spiromesifen在这些活性上没有显着差异。这意味着将草酰部分引入螺环四氢苯甲酸可能会导致新的生物活性特征。
Iron-Facilitated Oxidative Radical Decarboxylative Cross-Coupling between α-Oxocarboxylic Acids and Acrylic Acids: An Approach to α,β-Unsaturated Carbonyls
The first Fe-facilitated decarboxylative cross-coupling reaction between α-oxocarboxylicacids and acrylic acids in aqueous solution has been developed. This transformation is characterized by its wide substrate scope and good functional group compatibility utilizing inexpensive and easily accessible reagents, thus providing an efficient and expeditious approach to an important class of α,β-unsaturated

A photocatalytic decarboxylative/defluorinative reaction of α-trifluoromethyl alkenes with α-ketoacids and α-amino acids has been developed. The reaction occurs at room temperature under visible light irradiation, affording various γ,γ-difluoroallylic ketones and 1,1-difluorohomoallyl amines in good yields. The synthetic applications of the resulting functionalized gem-difluoroalkenes were also described
The disclosure generally relates to the novel compounds of formula I, including their salts, which inhibit HIV integrase and prevent viral integration into human DNA. This action makes the compounds useful for treating HIV infection and AIDS. The invention also encompasses pharmaceutical compositions and methods for treating those infected with HIV.
