2D NMR Study of Vindoline

Spectroscopy Letters, 1989
Abstract Two Dimensional COSY and HETCOR experiments have been performed on the alkaloid vindoline which allow the complete 1zH and 13C spectral assignments to be made. Proton-proton and proton-carbon coupling constants are also given.

Rearrangement of vindoline and derivatives in superacidic media

Tetrahedron, 1999
Abstract In HF - SbF5 at O°C, vindoline 1a and its deacetyl derivative 1b yield the cathovaline like compounds 4 and 5 , respectively, and the furanic diastereoisomers 2 and 3 . Fluoro derivatives (20S)- 10b-d rearrange in superacids to 4 (92%), 5 (60%) and to lactone 11 (58%), respectively ...

The Boger Synthesis of (-)-Vindoline

2013
The periwinkle-derived alkaloids vinblastine 2a and vincristine 2b are still mainstays of cancer chemotherapy. The more complex half of these dimeric alkaloids, vindoline 1, presents a formidable challenge for total synthesis. Building on his previous work (Organic Lett. 2005, 7, 4539), Dale L. Boger of Scripps/La Jolla devised (J. Am. Chem. Soc. 2010,

Spatial organization of the vindoline biosynthetic pathway in Catharanthus roseus

Journal of Plant Physiology, 2011
Vindoline constitutes the main terpenoid indole alkaloid accumulated in leaves of Catharanthus roseus, and four genes involved in its biosynthesis have been identified. However, the spatial organization of the tabersonine-to-vindoline biosynthetic pathway is still incomplete.
