Pd-mediated synthesis of 2-arylquinolines and tetrahydropyridines from modified Baylis–Hillman adducts
摘要:
We synthesized 2-arylquinolines and tetrahydropyridines via palladium-mediated Heck type reactions starting from the Baylis-Hillman adducts. 2-Arylquinolines were prepared via the Heck type cyclization followed by concomitant aerobic oxidation. (c) 2008 Elsevier Ltd. All rights reserved.
An efficient method for the synthesis of substituted quinolines is described. By FeCl3-promoted C–C bond formation, 2,3-disubstituted and 2,3,4-trisubstituted quinolines were successfully synthesized from the reaction between imines and electron-deficient alkynes in good yields. The reaction can also be performed in a sequential three-component manner by using aromatic amines and aromatic aldehydes

Fe3O4-TDSN-Bi(III) was utilized as an efficient and reusable catalyst for the regioselective one-pot synthesis of quinoline derivatives from arylamines, arylaldehydes and methyl propiolate under microwave irradiation and solvent-free conditions. Also, bis-quinolines were obtained in high yields from dialdehydes or diamines. Atom-economy, high to excellent yields, easy work-up, as well as simple catalyst
Fe 3 O 4 -TDSN-Bi(III)被用作有效和可重复使用的催化剂,用于在微波辐射和无溶剂条件下从芳基胺,芳基醛和丙炔酸甲酯区域选择性地一锅合成喹啉衍生物。同样,从二醛或二胺以高收率获得双喹啉。原子经济,高至优异的收率,易于后处理以及简单的催化剂回收和可重复使用性是此程序的关键特征。
Divergent Synthesis of Functionalized Quinolines from Aniline and Two Distinct Amino Acids
A practicable quinoline synthesis from aniline and two amino acids was developed for generating a wide range of quinolines with high efficiency and diversity. Thus, it facilitated the creations of pharmaceutical derivatives, photochemical active compounds, and challenging scaffolds. The concept of using two amino acids as heterocyclic precursors has been raised for the first time. Mechanistic studies
