In 2022,Murali, Karunanidhi; Prasad, Karnam Jayarampillai Rajendra published an article in ChemistrySelect. The title of the article was 《A Direct and Divergent Entrance to Aza Heterocycles On 3-Amino Carbazole》.Product Details of 614-16-4 The author mentioned the following in the article:
The product-switchable reagent-controlled construction of 1,4-Dihydropyridines and stereo-structured amino dienes decorated with carbazole moieties have been realized via coupling of 3-amino-9-ethylcarbazole with benzaldehyde and Me propiolate. Highly functionalized pyrido[3,2-b]carbazoles have been concisely synthesized in good yields via Et3N promoted single-pot assembly of 3-amino-9-ethylcarbazole with aryl/heteroaryl aldehydes and α-aryl-3-oxopropanenitrile. The structures of the synthesized products were confirmed by spectral data and elemental anal. In the experiment, the researchers used 3-Oxo-3-phenylpropanenitrile(cas: 614-16-4Product Details of 614-16-4)
3-Oxo-3-phenylpropanenitrile(cas: 614-16-4) has been used to produce 2-benzoyl-3-furan-2-yl-acrylonitrile. It is an active methylene compound, useful in heterocyclic synthesis, e.g. polyfunctional pyridines and pyrimidines.Product Details of 614-16-4
