Abstract
The functionalized 3,4-dihydroquinolin-2-one nucleus has been assembled in good to high yields through the sequential reaction of readily available N-Ts-o-aminobenzyl alcohols with 5-substituted Meldrum's acid derivatives under mild basic conditions. Highly diastereoselective synthesis of 3-substituted-4-phenyl-1-tosyl-3,4-dihydroquinolin-2(1H)-ones was accomplished from N-(2-(hydroxy(phenyl)methyl)phenyl)-4-methylbenzenesulfonamide under the same reaction conditions. Regarding the reaction mechanism, we hypothesized that the formation of dihydroquinolones proceeds through the in situ generation of aza-o-QMs followed by conjugate addition of enolate/cyclization/elimination of acetone and CO2.

Abstract
Perimidines are nitrogen-containing heterocyclic scaffolds with a wide range of
biological and material properties. Several synthetic transformations on perimidines afford
fused heterocycles. This review focuses on every aspect of perimidines, including different
synthetic procedures, reactions and applications, and covers the literature published up to the
year 2020, using more than 170 references.
