    使用金催化级联反应在水中绿色简便地组装各种稠合 N-杂环
    摘要:
    本研究描述了 AuPPh3Cl/AgSbF6 催化的胺亲核试剂和水中的炔酸之间的级联反应。这个过程以水作为唯一的副产物以高度经济的方式进行,并导致两个环的产生,同时在一次操作中形成三个新键。这种绿色级联工艺表现出有价值的特性,例如催化剂负载量低、产率高、成键效率高、选择性好、官能团耐受性好以及底物范围极其广泛。此外,这是在水中通过金催化从容易获得的材料生成吲哚/噻吩/吡咯/吡啶/萘/苯-稠合 N-杂环库的第一个例子。尤其,

  • Au(I)-Catalyzed Cascade Reaction Involving Formal Double Hydroamination of Alkynes Bearing Tethered Carboxylic Groups: An Easy Access to Fused Dihydrobenzimidazoles and Tetrahydroquinazolines

    A process involving gold(I)-catalyzed formal double hydroamination of alkynes, bearing a tethered carboxylic group, for the synthesis of fused dihydrobenzimidazoles and tetrahydroquinazolines has been developed. A series of transition metal catalysts have been screened for this transformation, and a catalyst system consisting of Ph3PAuCl (1 mol %) and AgOTf (1 mol %) was found to be the best. The procedure entails the reaction of easily accessible starting materials such as alkynoic acids and 1,2-diaminobenzenes/2-aminobenzylamines in the presence of the catalyst in 1,2-dichloroethane at 100 degrees C. In the case of alpha-substituted alkynoic acids, the corresponding products were obtained in high diastereoselectivities; the structure of the diastereomers has been unambiguously characterized by NMR techniques. The mechanism of the reaction is discussed, and the origin of the diastereoselectivities is addressed. It was observed that under the microwave irradiation conditions, the reaction time is significantly shortened (0.5 h).
