标题:New α-Selective Thermal Glycosylation Of Acetyl-Protected 2-Acetamido-2-Deoxy-β-D-Glucopyranosyl Diphenylphosphinate
摘要:This Paper Describes New Alpha-Selective Thermal Glycosylation Using Acetyl-Protected 2-Acetamido-2-Deoxy-Beta-D-Glucopyranosyl Diphenylphosphinate (4) As A Glycosyl Donor. When The Glycosylation Of 4 With 1-Hexanol Was Carried Out Under Various Conditions,The Conditions Using Trimethylsilyl Trifluoromethanesulfonate As A Promoter In Nitromethane At Reflux Temperature Were Most Suitable For The Formation Of The Alpha Anomer. The Glycosylation Of 4 With The Other Common Alcohols Gave Corresponding Alpha-Glycosides In Relatively High Yields Under The Conditions. When Cholesterol,A Very Steric Hindered Alcohol,Was Used As A Glycosyl Acceptor,Alpha-Glycoside Was Also Produced Predominantly. (C) 2000 Elsevier Science Ltd. All Rights Reserved.
