A series of new N‐cyclopropyldecahydroacridine‐1,8‐dione derivatives were synthesized by one‐pot reaction of aromatic aldehyde, dimedone (or 1,3‐cyclohexanedione) and cyclopropanamine in solution of glycol and water under microwave irradiation with excellent yields (78‐94%) and short reaction time (5‐10 min). 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

Indium(III) chloride catalyzed one-pot synthesis of 12-aryl/alkyl-8,9,10,12-tetrahydrobenzo[a]xanthene-11-one and 8,10-dimethyl-12-aryl-8,12-dihydro-7-oxa-8,10-diazabenzo[a]anthracene-9,11-dione derivatives have been achieved by three component cyclocondensation of aldehydes, β-naphthol and cyclic 1,3-dicarbonyl compounds under solvent free condition in high yields. P2O5 too has been found as an effective catalyst towards this transformation. 相似文献

A series of 3‐methyl‐1,4‐disubstituted‐4,5‐dihydro‐1H‐pyrazolo[3,4‐b]pyridine‐6(7H)‐ones was synthesized via the three‐component reaction of aldehyde, 3‐methyl‐1‐phenyl‐1H‐pyrazol‐5‐amine, and Meldrum's acid catalyzed by L ‐proline. This protocol has the advantages of easier work‐up, milder reaction conditions, and high yields. J. Heterocyclic Chem., (2011). 相似文献

The diazonium salt of 2‐aminophenol 2 was coupled in situ with malononitrile derivatives 3a‐d , 2‐cyanomethylthiazolin‐4‐one 9 , 2‐cyanomethylbenzimidazole 11a , and 2‐cyanomethylbenzothiazole 11b to give 2‐amino[1,4,5]benzoxadiazepine derivatives 6a‐d, 10 and 12a,b via a one‐pot reaction. 相似文献

A series of dispiropyrrolidine derivatives were synthesized via the three‐component 1,3‐dipolar cycloaddition reaction of isatin, sarcosine and 5‐arylidene‐1,3‐thiazolidine‐2,4‐dione or 5‐arylidene‐4‐thioxo‐1,3‐thiazolidine‐2‐one in ethanol under ultrasound irradiation. This protocol has the advantages of mild reaction conditions, higher yields, and shorter reaction time. J. Heterocyclic Chem., (2011). 相似文献

L ‐Proline is found to be an efficient catalyst for the synthesis of tetrahydrofuro[3,4‐b]quinoline‐1,8(3H,4H)‐dione derivatives. This protocol is novel and has the advantages of mild condition, high yield, and easy operation. J. Heterocyclic Chem., (2012). 相似文献

A sulfonated magnetic cellulose‐based nanocomposite was applied as an efficient, inexpensive and green catalyst for the one‐pot three‐component synthesis of 7‐aryl‐8H ‐benzo[h ]indeno[1,2‐b ]quinoline‐8‐ones starting from 1,3‐indanedione, aromatic aldehydes and 1‐naphthylamine under solvent‐free conditions in high yields (79–98%) within short reaction times (2–5 min). The nanobiostructure catalyst can be easily separated from the reaction mixture by using an external magnet and reused several times. 相似文献

(Bromodimethylsulfonium) bromide–catalyzed one‐pot multicomponent reaction of 2‐aminopyridine with aromatic aldehyde(s) and TMSCN yielding N‐benzylidene‐2‐phenylimidazo[1,2‐a]pyridines exclusively has been described. The reaction is solvent free, versatile, and takes significantly short time. J. Heterocyclic Chem., (2011). 相似文献
