摘要:

The chemical shifts of the NHprotons for a series of substituted 2-quinolone derivatives bearing no 4-methyl substituent have been studied. The 8-methyl substituent almost exclusively causes the Inhibition of hydrogen bonding. Some methoxy substituted 2-quinolone derivatives have also been studied as model compounds for the identification of quinolone alkaloids.
