  Synthesis of Novel 1,3,5-Tris(arylazo)benzenes via Pd-Catalyzed Couplings and Cu(I)-Mediated Direct Oxidations

  摘要：

  A series of novel 1,3,5-tris-azobenzenes were prepared from 1,3,5-trihalobenzene via Pd-catalyzed couplings of N-Boc aryl hydrazines and subsequent Cu(I)-mediated direct oxidations. The oxidation of tris-arylhydrazide provided the azobenzene as a mixture of all four of the possible E/Z-isomers; [E,E,E]-, [E,E,Z]-, [E,Z,Z]-, and [Z,Z,Z]-1,3,5-tris-azobenzenes. A slow removal of the solvent in the dark transformed the isomers into the all-trans, [E,E,E]-isomer.

  The present invention relates to copper-catalyzed carbon-heteroatom and carbon-carbon bond-forming methods. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of an amide or amine moiety and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In additional embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between a nitrogen atom of an acyl hydrazine and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In other embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-nitrogen bond between the nitrogen atom of a nitrogen-containing heteroaromatic, e.g., indole, pyrazole, and indazole, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. In certain embodiments, the present invention relates to copper-catalyzed methods of forming a carbon-oxygen bond between the oxygen atom of an alcohol and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. The present invention also relates to copper-catalyzed methods of forming a carbon-carbon bond between a reactant comprising a nucleophilic carbon atom, e.g., an enolate or malonate anion, and the activated carbon of an aryl, heteroaryl, or vinyl halide or sulfonate. Importantly, all the methods of the present invention are relatively inexpensive to practice due to the low cost of the copper comprised by the catalysts.

  CuI/4-hydroxy-l-proline-catalyzed coupling of aryl bromides and N-Boc hydrazine takes place in DMSO at 80 °C to give N-aryl hydrazides. When aryl iodides are employed, this reaction completes at 50 °C and no ligand is required. Under the catalysis of CuI/4-hydroxy-l-proline, the coupling reaction of aqueous ammonia with aryl bromides proceeds smoothly at 50 °C to afford primary arylamines. In this

  CuI / 4-羟基-1-脯氨酸催化的芳基溴化物与N- Boc肼的偶合反应在DMSO中于80°C进行，得到N-芳基酰肼。当使用芳基碘化物时，该反应在50℃下完成并且不需要配体。在CuI / 4-羟基-1-脯氨酸的催化下，氨水与芳基溴化物的偶联反应在50℃下顺利进行，得到伯芳基胺。在这种情况下，发现K 2 CO 3是比Cs 2 CO 3更好的碱。这些过程允许组装N带有多种官能团的-芳基酰肼和伯芳基胺包括羟基，胺基，三氟甲基，酯基，硝基和酮。
