标题:可见光促进 C(Sp3)−h 键无金属合成(杂)芳香腈**
摘要:C(Sp 3 )−h 键的无金属活化生成增值产品在有机合成中至关重要.我们报道了使用市售有机染料 2,4,6-三苯基吡喃鎓四氟硼酸盐 (Tpp) 通过光催化过程将甲基芳烃转化为相应的芳基腈.应用这种方法,在不含金属和氰化物的条件下,可以以非常好到优异的收率合成多种氰基苯.我们通过 50 多个示例证明了该方法的范围,包括药物分子(塞来昔布)的后期功能化和l-薄荷醇,氨基酸和胆固醇衍生物等复杂结构.此外,所提出的合成方案适用于克级反应.除了甲基芳烃之外,还展示了醛,醇和肟氰化的选定示例.使用时间分辨发光猝灭研究,控制实验,核磁共振波谱以及动力学研究进行了详细的机理研究,所有这些都支持了所提出的催化循环.

标 题:Solid-phase synthesis of N-alkyl amides
发明人：BROWN EDWARD G; NUSS JOHN M
权利人:CHIRON CORP
摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.

摘要:A method for synthesis of secondary alcohols is provided for pharmaceutical secondary alcohol by addition of organoboronic acids with aldehydes in presence of the cobalt ion and bidentate ligands as the catalyst. In addition, an enantioselective synthesis method for secondary alcohols is also herein provided in the present invention. The present invention has advantages in using less expensive cobalt ion and commercially available chiral ligands as the catalyst, wide scope of organoboronic acids and aldehydes compatible with this catalytic reaction and achieving excellent yields and/or enantiomeric excess.

摘要:Described are methods for preparing a deuterated aldehyde using N-heterocyclic carbene catalysts in a solvent comprising D 2 O. The methods may be used to convert a wide variety of aldehydes (e.g., aryl, alkyl, or alkenyl aldehydes) to C-1 deuterated aldehydes under mild reaction conditions without functionality manipulation.

标题:Use of functionalized onium salts as a soluble support for organic synthesis
发明人：VAULTIER MICHEL; GMOUH SAID; HASSINE FATIMA
权利人:CENTRE NAT RECH SCIENT; UNIV RENNES
摘要:The invention relates to the use of a onium salt functionalized by at least one organic function, as a soluble support, in the presence of at least one organic solvent, for organic synthesis of a molecule, in a homogenous phase, by at least one transformation of said organic function. The onium salt enables the synthesized molecule to be released. The onium salt is present in liquid or solid form at room temperature and corresponds to formula A₁⁺, X₁^-, wherein A₁⁺ represents a cation and X₁^- represents an anion.
