which can be identified by nuclear magnetic resonance spectroscopy in dimethyl sulphoxide. This led to syntheses of balfourodine, isobalfourodine, and platydesmine, and the constitution of the latter alkaloid was thereby established. Some of the results have been reported briefly.
与N-甲基-(3-甲基丁-2-烯基)
喹诺酮的氧化环化相反,缺少N-甲基的相应

生物的混合物,通过核磁共振光谱法在
二甲亚砜中鉴定。这导致了balfourodine,isobalfourodine和platydesmine的合成,从而确定了后者的
生物碱的组成。一些结果已被简要报道。
