Cularine alkaloids biosynthesis

The biosynthesis of cularine alkaloids (239) by phenolic oxidation also proceeds via the dienone compound (Scheme 4) similar to the aporphine or morphinane alkaloids. [Pg.370]

Several routes have been proposed for the biosynthesis of cularine alkaloids, involving one of four types of biogenetic precursors ... [Pg.317]

Precursors A and B are thought to be the starting compounds for the most common cularines, while C and D are believed to be precursors in the biosynthesis of specific types of cularine alkaloids. [Pg.317]

In conclusion, oxidized cularine alkaloids might be formed by reactions analogous to those occurring in aporphine biosynthesis (73), according to the following general sequence ... [Pg.322]
