Regiospecific synthesis of three quercetin O-β-glucosides of N-acetylglucosamine

The regiospecific synthesis of three quercetin O-β-glucosides of N-acetylglucosamine has been achieved in good yield. Selective di- and tri-O-benzylation of quercetin followed by O-glycosylation with 2-acetamido-3,4,6-tri-O-acetyl-2-deoxy-α-d-glucopyranosyl chloride under phase-transfer catalysis conditions yielded, after deacetylation and debenzylation, 3-, 3′- and 4′-glycosylated quercetin.

Synthesis of quercetin 3-O-[6"-O-(trans-p-coumaroyl)]-β-D- Glucopyranoside

This report describes the efficient synthesis of quercetin 3-O-[6"-O-(trans-pcoumaroyl)]- β-D-glucopyranoside 1 (isoquercitrin coumarate), an acylated quercetin glycoside possessing antihypertensive, antidiabetic, and tyrosinase inhibitory activities. The synthesis is initiated from commercially available quercetin via regioselective benzylation of quercetin to produce 4', 7-di-O-benzylquercetin (4). Through 4, 1 was successfully achieved via selective β-glycosylation of the 3-OH, acylation of 6"-OH, and finally debenzylation via catalytic transfer hydrogenation. Taylor & Francis Group, LLC.
