Krupkova, Sona published the artcileSolid-Phase Synthesis of 3-Hydroxy-6-Nitroquinolin-4(1H)-ones with Two Diversity Positions, Product Details of C7H3ClFNO4, the main research area is anthranilic acid chloro resin bound amination esterification cyclization rearrangement; quinolinone hydroxy nitro amino aryl preparation solid phase.
The efficient solid-phase synthesis of 3-hydroxy-2,7-disubstituted-6-nitroquinolin-4(1H)-ones I [R1R2 = (CH2)5, (CH2)2O(CH2)2, R3 = 4-H2N-3,5-Cl2, 4-O2N; etc.] using Rink amide resin was described. The synthesis started from immobilized 4-chloro-5-nitroanthranilic acid, which after nucleophilic replacement of the chlorine atom with various amines R1R2NH and subsequent esterification with bromoacetophenones, afforded substituted phenacyl anthranilates. Their cyclization by heating in sulfuric acid or trifluoroacetic acid gave the corresponding hydroxyquinolinones in excellent purity.
