Pubescenoside B → (2R,3S,4R,5R)-2,3,4,5,6-pentahydroxyhexanal

Participants

Reaction Steps

Acid hydrolysis of pubescenoside B: Compound 2 (15 mg) was hydrolyzed in a manner similar to that described for compound 1, yielding caffeic acid, D-(+)-glucose {[α]D21=+33.1° (c=0.1, H2O), determined after being dissolved in H2O for 24 hours} and compound 1a which was identified by comparing its 1H-NMR data with those described in the reference13.
