one-pot two-component synthesis under solvent-free conditions in good yields by the reaction of a variety of aryl or heteroaryl amines and aryl vinyl ketones. A combinatorial type approach for a one-step microwave reaction has been developed where a ring-closing condensation is followed by a spontaneous aromatization to afford the functionalized aryl substituted 1,8-naphthyridines and quinolines.
The synthesis of 2,4-diarylquinolines is reported by employing arylamine, aryl aldehyde, and aryl acetylene using 30 mol% p-toluenesulfonic acid monohydrate (p-TSA·H2O) as a catalyst at 110 °C temperature undersolvent-freeconditions via a one-pot three-component reaction. The salient features of the present protocol are the nonrequirement of a metal catalyst, additive, solvent, and inert atmospheric
报道了以30 mol%对甲苯磺酸一水合物( p -TSA·H 2 O)为催化剂,在110 °C无溶剂条件下,以芳胺、芳基醛和芳基乙炔为催化剂合成2,4-二芳基喹啉。通过一锅三组分反应的条件。本协议的显着特点是不需要金属催化剂、添加剂、溶剂和惰性大气反应条件、良好的产率、底物范围和较短的反应时间。用30 mol%对甲苯磺酸一水合物( p -TSA·H 2O) 在无溶剂条件下作为催化剂使三组分反应足够有效地形成 2,4-二芳基喹啉,而无需任何重金属催化剂或添加剂的参与。
