Chemoenzymatic synthesis and stereochemistry of aleppotrioloside, a naturally occurring glucoside
摘要:
The stereochemistry of aleppotrioloside, a naturally occurring glucoside, has been determined as (3S)-3-[(1S)-1-hydroxyethyl]-4-methyl-1,4-pentanediol-1-O-beta-D-glucopyranoside by its synthesis based on two key enzymatic reactions: Pseudomonas fluorescens lipase (PFL) catalyzed enantioselective resolution of an aglycone precursor and transglucosylation of the aglycone by thermophilic beta-glycosidase from Sulfolobus solfataricus.
