Add time:07/19/2019 Source:sciencedirect.com
The first total synthesis of dioncophylline A (previously “triphyophylline”) and some selected stereoisomers is described, using an intramolecular-type mixed aryl coupling method via ester-type prefixed molecular moieties. Simultaneously, this synthesis establishes the complete (revised) stereostructure of dioncophylline A as 1a, which is thereby the first fully elucidated naphthylisoquinoline alkaloid of Dioncophyllaceae.
