A Simple One-Pot Synthesis of New Imidazol-2-yl-1<i>H</i>-quinolin-2-ones from the Direct Reaction of 2-Chloroquinolin-3-carbaldehyde with Aromatic<i>o</i>-Diamines
An alternative and general one-potsynthesis of a library of novel imidazol-2-yl-1H-quinolin-2-one derivatives was performed in 70% aqueous acetic acid by the direct reaction of 2-chloroquinolin-3-carbaldehyde with aromatic o-diamines. Experiments showed that adding Amberlyst ® -15 (20 % w/w) to the reaction media increased both the speed of reaction as well as the yield of products. Both DFT theoretical
