  • Selective synthesis of trisubstituted pyrroles through the reactions of alkynyl Fischer carbene complexes with oxazolones

    An efficient and simple synthesis of novel trisubstituted 1H-pyrroles 4a-qvia 1,3-dipolar cycloaddition of Δ3-trifluoromethyloxazolones 2a-d with both chromium and tungsten alkynyl Fischer carbene complexes (1a-h) is described. An unexpected and unreported -CF3 group elimination process was observed in the pyrrole structure. Our experimental and theoretical data suggested that the metal fragment may
    描述了Δ3-三甲基恶唑酮2a-d与炔基舍尔卡宾配合物(1a-h)的新型三取代的1H-吡咯4a-qvia 1,3-偶极环加成反应的高效简单合成。在吡咯结构中观察到出乎意料且未报告的-CF 3基团消除过程。我们的实验和理论数据表明,属碎片可能是造成这种现象的原因。偶极环加成有效地进行以产生单个区域异构体,该区域异构体通过NMR和单晶X射线衍射研究明确地确定。然而,带有α,β,γ,δ-不饱和部分的炔基卡宾与过量的恶唑酮2a的反应产生了多环化合物6,该多环化合物6通过涉及1,6-,1,4-和1的级联反应推测地形成。

    A novel synthetic methodology is reported for the synthesis of fluorescent pyrrolo[1,2-a]pyrimidines. Fischer carbene complexes served as the synthetic platform for (3+3) cyclization to form the heterocyclic moiety. The reaction process furnished two products, their ratio being modulated by the metal, base, and solvent. The selectivity exhibited was studied by analyzing the potential energy surface

    instead of the expected Ir(I) compound [Ir(COD)L]; all the new Ir(III) were prepared in high yields as microcrystalline solids. They were all stable under laboratory atmosphere, lasting for weeks in solution and for months in solid state. The structure of each compound was examined by 1D and 2D nuclear magnetic resonance (NMR) and high-resolution mass spectrometry (HRMS). Complex 1k was selected for an

  • A new, simple access to pentacarbonyl(3-aminoallenylidene)chromium complexes
    作者:Frank Stein、Michael Duetsch、Ehmke Pohl、Regine Herbst-Irmer、Armin de Meijere
    DOI:10.1021/om00031a028
    日期:1993.7
    Primary and secondary amines react with pentacarbonyl(1-ethoxy-1-alkynylcarbene)chromium complexes 1a-g to give pentacarbonyl(3-aminoallenylidene)chromium complexes 11-18 and pentacarbonyl[ethoxy(2-aminoethenyl)carbene]chromium complexes 3-10. Crystal structures of two relevant examples are reported. The product ratio is influenced by the size of the substituent on the acetylene terminus and in the amine, the basicity of the amine, and the reaction temperature. Reaction of 1a-c,f with lithium amides gave even higher yields of the corresponding allenylidene complexes. Addition of dimethylamine to allenylidene complexes 15f and 13a gave quantitative yields of bis(dialkylamino)ethenylcarbene complexes (E/Z)-23 and (E)-24.
