Synthesis of 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles and features of their NMR spectra
Shkoor, Mohanad; Su, Haw‐Lih; Ahmed, Suzan; Hegazy, Sarah ( Wiley , 2019 , Article)Two different methods leading to 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles were investigated. Reactions of 3-aminocrotonirile with substituted salicylaldehydes provided 5-oxo-5H-chromeno[3,4-c]pyridine-1-carbonitriles ...
