The Name is 3-Nitrobenzaldehyde. Through research, I have a further understanding and discovery of 99-61-6. Safety of 3-Nitrobenzaldehyde
In this research, a number of new and known chromenopyrano [2,3-b]pyridine derivatives have been prepared. Initially, according to the reported procedure, pyrano [2,3-c] chromene derivatives were synthesized by the reaction between 4-hydroxycoumarin, aromatic aldehydes and malononitrile using silica sodium carbonate (SSC) as the catalyst. Next, the prepared pyrano [2,3-c] chromenes were reacted by dimethyl acetylenedicarboxylate (DMAD) or cyclohexanone in the presence of sodium carbonate to produce chromenopyrano [2,3-b]pyridine derivatives. The presented protocol avoids the use of expensive catalysts and gives useful potentially bioactive heterocycles in excellent to high yields.
