Photoinduced hydroarylation of alkenes is an appealing synthetic strategy for arene functionalization. Herein, we demonstrated that aryl radicals generated from electron‐deficient aryl chlorides/bromides could be trapped by an array of terminal/internal aryl alkenes in the presence of [Pt(O^N^C^N)] under visible‐light (410 nm) irradiation, affording anti‐Markovnikov hydroarylated compounds in up to
烯烃的光诱导加氢芳基化是芳烃官能化的一种有吸引力的合成策略。在此,我们证明了在可见光下,[Pt(O ^ N ^ C ^ N)]存在下,电子不足的芳基氯化物/溴化物产生的芳基自由基可能被一系列末端/内部芳基烯烃捕获(410)。纳米)辐射,以高达95%的收率提供抗马氏化学水解的化合物。此外,还开发了一种用于[Pt(O ^ N ^ C ^ N)]催化的丙烯酰胺分子内光环化反应的化合物,以提供结构多样的3,4-二氢喹啉酮。
Schmidt Reaction on Substituted 1-Indanones / N-Alkylation: Synthesis of Benzofused Six-membered Ring Lactams and their Evaluation as Antimicrobial Agents
synthesized some benzofused six membered ring lactams and their alkyl derivatives as a trial to obtain valuable precursors for the discovery of future antimicrobial drugs. Methods: The substituted lactams 3,4-dihydro-2(1H)-quinolinones 3a-c and 3,4-dihydro-1(2H)- isoquinolinones 4a-c were synthesized by Schmidtreaction on indanones 2a-c which were obtained by Friedel-Crafts reaction on β-substituted α,β-unsaturated

An efficient silver-catalyzed tandem decarboxylative radical addition/cyclization of oxamic acids with alkenes has been developed. This method provides a novel and straightforward protocol toward a variety of 4-aryl-3,4-dihydroquinolin-2(1H)-ones, 4-(α-carbonyl)-3,4-dihydroquinolin-2(1H)-ones, and quinolin-2(1H)-ones in aqueous solution.
