Zh. Jiang et al., RHOIPTELEANIN-A AND RHOIPTELEANIN-E, DIMERIC ELLAGITANNINS FORMED BY INTERMOLECULAR C-C OXIDATIVE COUPLING FROM RHOIPTELEA-CHILIANTHA, Journal of the Chemical Society, Chemical Communications, (14), 1995, pp. 1467-1468
The first dimeric ellagitannins, rhoipteleanins A and E, generated bio
genetically by intermolecular C-C oxidative coupling, are isolated fro
m the fruits of Rhoiptelea chiliantha and structurally elucidated on t
he basis of spectroscopic and chemical evidence.
