parts of a new species from the genus Agathosma yielded skimmianine and two new alkaloids 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
摘要 从 Agathosma 属的一个新物种的地上部分产生了 skimmianine 和两种新的生物碱,通过光谱数据和合成鉴定为 4,6-二甲氧基-1-甲基-2(1H)-喹啉酮和 2,6-二氢-9-甲氧基-2,2,6-trimethyl-5H-pyrano[3,2c]quinolin-5-one。进一步合成了相关结构,对八种合成结构的 2D NMR 研究使我们能够更正文献中出现的一些数据。
