A simple, efficient and convenient one‐pot synthesis of 2,3‐dihydroquinazolin‐4(1H)‐one derivatives under solvent‐free and catalyst‐free conditions by the reaction of aromatic aldehydes, isatoic anhydride, and ammonium acetate was reported. The advantages of this protocol include short reaction time, mild reaction conditions, easy work‐up, high yields, and environmental friendliness. J. Heterocyclic Chem., (2011). 相似文献

A clean and expeditious route for the synthesis of 2‐aryl‐4‐ferrocenyl‐quinoline derivatives through microwave‐assisted multicomponent reaction of ferrocenecarboxaldehyde with ketone and dimedone in the presence of ammonium acetate using water as reaction media at 100°C is described. This procedure lends itself well to combinatorial methods, providing the target heteropolymetallic compounds in excellent yield. J. Heterocyclic Chem., (2011). 相似文献

A series of pyrimidoquinoline derivatives were synthesized through one‐pot condensation of 2,6‐diaminopyrimidin‐4‐one, aldehyde and cyclic a 1,3‐dicarbonyl compound in glycol under microwave irradiation without catalyst. The protocol in the absence of catalyst has the advantage of good yield (87‐95%), short reaction time (4‐7 min) and an environmentally friendly technique. 相似文献

A series of 4‐aryl‐3,7,7‐trimethyl‐1‐phenyl‐7,8‐dihydro‐1H‐pyrazolo[3,4‐b]quinolin‐5(6H)‐ones were synthesized via the three‐component reaction of aromatic aldehydes, 5,5‐dimethyl‐1,3‐cyclohexandione and 5‐amino‐3‐methyl‐1‐phenylpyrazole in ionic liquid without using any catalyst. This protocol has the advantages of easier work‐up, milder reaction conditions, short reaction time, and environmentally benign procedure. J. Heterocyclic Chem., (2011). 相似文献

A highly efficient one-pot, two-step microwave procedure has been developed for the synthesis of 4-substituted 1-heteroarylpiperazines. Microwave heating of heteroaryl chlorides with 1,4-diazabicyclo[2.2.2]octane (DABCO) at 160 °C for 15 min yielded 1-heteroaryl-4-(2-chloroethyl)piperazines, which could be further reacted with various nucleophiles, again under microwave irradiation conditions, to give an array of 4-substituted 1-heteroarylpiperazines in good to excellent yields. 相似文献

Abstract An efficient and convenient method for the preparation of 3-benzylquinazolin-4(1H)-one derivatives under solvent-free and catalyst-free conditions by the reaction of isatoic anhydride, benzylamine, and aromatic aldehydes was reported. In reported papers, ammonia water, ammonium salt, and aromatic amine were often used to synthesize quinazolin-4(1H)-one derivative, but benzylamine was seldom used in this synthesis. This article offers a green method for the synthesis of 3-benzylquinazolin-4(1H)-one derivative used benzylamine as starting material. This methodology has the advantages of short reaction time, mild reaction conditions, easy work-up, and environmental friendliness. 相似文献

A series of 4‐aryl‐3,7,7‐trimethyl‐1‐phenyl‐7,8‐dihydro‐1H‐pyrazolo[3,4‐b]quinolin‐ 5(6H)‐ones were synthesized by the three‐component reaction of aromatic aldehydes, 3‐methyl‐1‐phenyl‐1H‐pyrazol‐5‐amine, and 5,5‐dimethyl‐1,3‐cyclohexandione in the presence of sodium 1‐dodecanesulfonate in aqueous medium. Compared to the previous methods, this new protocol has the advantages of convenient operation, higher yields, lower cost, and environmentally benign procedure. J. Heterocyclic Chem., (2012). 相似文献
