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- 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。

hetaryl fragments were easily prepared from corresponding aldimines derived from commercially available aromatic aldehydes and anilines. 2-Furyl substituted anilines showed very good antifungal activities against dermatophytes, particularly against Trichophyton rubrum (MIC=3.12-6.25microg/mL). In addition, all active compounds, 45-47, 73, and 74, were tested for cytotoxic activities against breast (MCF-7)

1,3-Dimethyluracils having a nitrile oxide moiety or a nitronomethyl group at C-5 and an N-aryl-2-thienylmethylamino group at C-6 undergo an intramolecular cycloaddition reaction to give novel uracil-fused heterocycles.
