The structures (including conformation and absolute configuration) of myrtine and epimyrtine, quinolizidine alkaloids from Vaccinium myrtillus, are reported. The two bases are obtainable from pelletierine by Mannich condensation with acetaldehyde, or can be derived stereospecifically by 1,4-nucleophilic addition to enaminones. They have been resolved with tartaric acid. The isomerization of myrtine
报道了来自牛痘越桔的桃金娘碱和表myrine,奎尼嗪核碱生物碱的结构(包括构象和绝对构型)。这两个碱可通过曼尼希与乙醛的曼尼希缩合而从小丸碱中获得,或可通过与烯胺酮的1,4-亲核加成反应立体定向获得。他们已经用酒石酸解决了。讨论了桃金娘碱的异构化。
