摘要:

The13C n.m.r. spectra of a series of 1-methyl-2-quinolone derivatives are presented. The N-CH3and 8-CH3carbons each exhibit a characteristicperideshielding effect. The substituent effects caused by aperi-methyl group have been discussed and compared with effects previously observed in the naphthalene series.
