Recent developments in syntheses of the post-secodine indole alkaloids. Part III: Rearranged alkaloid types

and formal total synthesis of the post-secodine indole alkaloids focuses on types of rearranged alkaloids, i.e. on the skeletons with altered connectivities next to the indol of melodane, goniomitine, chippiine/di...

Glycosides of benzodioxole-indole alkaloids from Narcissus having axial chirality

Glycosides of benzodioxole-indole alkaloid 6-hydroxy-galanthindole having axial chirality were isolated from Narcissus. The structure, including absolute configuration, was determined by means of extensive spectroscopic data, and co...

Solution of the multistep pathway for assembly of corynanthean, strychnos, iboga, and aspidosperma monoterpenoid indole alkaloids from 19E-geissoschizine

Monoterpenoid indole alkaloids (MIAs) possess a diversity of alkaloid skeletons whose biosynthesis is poorly understood. A bioinformatic search of candidate genes, combined with their virus-induced gene silencing, targeted ...
