parts of a new species from the genus Agathosma yielded skimmianine and two newalkaloids which were identified by means of spectral data and synthesis as 4,6-dimethoxy-1-methyl-2(1H)-quinolinone and 2,6-dihydro-9-methoxy-2,2,6-trimethyl-5H-pyrano[3,2 c ]quinolin-5-one. Further related structures were synthesized and a 2D NMR study on the eight synthetic structures enabled us to correct some of the data
