A series of key intermediates of quercetin analogues were designed and synthesized in this paper.Acetophenone derivatives were got by using phloroglucinol as raw material through the Hoesch reaction and dimethyl sulph...
Amino acid benzyl ester p-toluenesulfonic acids were synthesized under microwave irradiation condition by reaction of four amino acids with benzyl alcohol and p-toluenesulfonic acid,and then reacted with the N-phthalo...
The hydrochloride of 1-(1-amino-3-methyl)butyl borate pinacol is prepared by using the isobutylbromide to form the Grignard agent.The product is protected with the pinacol,then reacted with the lithium diisopropylamid...
The synthetic route of 3’-amino carboxylate hydrochloride of quercetin is improved.Using benzyl bromide to partly protect the hydroxyl groups,the protected quercetin then react with a series of Boc protected amino ac...
