Revision of Structures of some Schumanniophyton Alkaloids.
The structures of isoschumanniophytine and N-methylschumannificine have been revised on the basis of NOE experiments and their reaction with Gibb's reagent. Revised structures are also proposed for schumannificine, anhydroschumannificine and N-methylanhydroschumannificine.
