Kaur, Jasreen; Bariwal, Jatinder; Bedi, Preet Mohinder Singh; Kaur, Maninderjit; Kapoor, Amit; Kaur, Mandeep; Verma, Poonam published an article in 2017, the title of the article was Highly efficient synthesis of pyranoquinoline derivatives catalyzed by piperidine.Application In Synthesis of 2-((1H-Indol-3-yl)methylene)malononitrile And the article contains the following content:
A mild and efficient method for the synthesis of substituted pyranoquinolones I [R = 2-furyl, Ph, 4-ClC6H4, etc.; R1 = CN, COOEt] via a two-component reaction of 4-hydroxy-1-methyl-2(1H)-quinolinone and intermediate arylidenes catalyzed by piperidine was described. The reaction commenced very fast after heating of reaction mixture at 鈮?0掳C for 2-3 h and gives high yields. This new procedure had the advantages of mild reaction condition, high yields and metal-free catalyst. The experimental process involved the reaction of 2-((1H-Indol-3-yl)methylene)malononitrile(cas: 75629-62-8).Application In Synthesis of 2-((1H-Indol-3-yl)methylene)malononitrile
The Article related to pyranoquinolone preparation, Heterocyclic Compounds (More Than One Hetero Atom): Fused-Ring Systems With Two Or More Hetero Atoms, No More Than One Hetero Atom Per Ring and other aspects.Application In Synthesis of 2-((1H-Indol-3-yl)methylene)malononitrile
