Roxbin B is cuspinin: Structural revision and total synthesis

Prompted by the outcome that the synthesized roxbin B was not identical to the natural roxbin B, the structural determination process and spectral data were re-examined, with the finding that roxbin B was very likely to be 1-O-galloyl-2,3-(R);4,6-(S)-bis-

Ellagitannin Chemistry. The First Total Chemical Synthesis of an O(2),O(3)-Galloyl-Coupled Ellagitannin, Sanguiin H-5

The biomimetic synthesis of sanguiin H-5 (1) was accomplished through the diastereoselective formation of the crucial biphenyl carbon-carbon bond between galloyl moieties at the O(2) and O(3) positions of an appropriately protected glucose-derived precursor.Furthermore, the β-anomeric galloyl linkage was established with complete stereochemical control.
