Ag/g-C3N4 nanometric semiconductor as the photocatalyst, 2-arylquinolines were synthesized through a photoxidation-Povarov cascade reaction of N-benzylanilines and alcohols under visible lightirradiation. Under the blue light of a 3 W LED, good yields were achieved for various substrates in oxygen at room temperature. This methodology provides a green and mild alternative for the formation of 2-arylquinoline
以Ag / g-C3N4纳米半导体为光催化剂,在可见光照射下,通过N-苄基苯胺和醇的光氧化-Povarov级联反应合成了2-芳基喹啉。在3 W LED的蓝光下,室温下在氧气中各种衬底的产率都很高。该方法为2-芳基喹啉衍生物的形成提供了绿色和温和的替代方法。值得注意的是,Ag / g-C3N4纳米复合材料可以方便地回收并以令人满意的产率重复使用数次。

A variety of diallylanilines are shown to undergo cobalt-carbonyl catalyzed rearrangement to quinolines. Diallylanilines are also used as allyl transfer reagents to convert benzaldimines into quinolines. Substitution in the 2- and 3-positions of the quinoline is featured in all transformations.

diastereo- and enantioselectiveIr-catalyzedhydrogenation of unfunctionalized 2,3-disubstituted quinolines, especially 3-alkyl-2-arylquinolines, has been realized. The success of this hydrogenation is ascribed to the use of a structurally fine-tuned chiral phosphine-phosphoramidite ligand with a (Sa)-3,3'-dimethyl H8-naphthyl moiety and (Rc)-1-phenylethylamine backbone. The hydrogenation displayed broad

reaction following a tandemprocess integrating isomerization of allylic alcohols and oxidative cyclization of 2-aminobenzyl alcohol. A new tandem catalytic process has been established for the synthesis of quinolines. This process utilizes the [IrCp*Cl2]2/KOH catalyzed isomerization/cyclization of allylic alcohols with 2-aminobenzyl alcohol. Both the secondary and primary allylic alcohols were investigated
