Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Synlett called Easy Access to Quinolin-2(1H)-ones via a One-Pot Tandem Oxa-Michael-Aldol Sequence, Author is Jarrige, Lucie; Zaied, Siwar; Merad, Jeremy; Blanchard, Florent; Masson, Geraldine, which mentions a compound: 20028-53-9, SMILESS is NC1=CC=C(Cl)C=C1C=O, Molecular C7H6ClNO, Reference of 2-Amino-5-chlorobenzaldehyde.
An efficient strategy for the synthesis of a variety of quinolin-2(1H)-one derivatives was developed. The reaction proceeded from cinnamide derivatives via a tandem reaction in the presence of NaOH to afford the corresponding 2-quinolin-2(1H)-one derivatives in good to excellent yields.
Although many compounds look similar to this compound(20028-53-9)Reference of 2-Amino-5-chlorobenzaldehyde, numerous studies have shown that this compound(SMILES:NC1=CC=C(Cl)C=C1C=O), has unique advantages. If you want to know more about similar compounds, you can read my other articles.
