[摘要]:A mild and efficient protocol for the stereoselective synthesis of N-glycosides of enone sugars has been developed. The reaction proceeds to provide N-glycosides of enone sugars in moderate to good yields with preferential alpha-anomeric selectivity. Additionally, applications of the N-glycosides of enone sugar derivatives as precursor to assemble some biochemically functional derivatives have also been explored. This includes the use of N-glycosides of enone sugars as reactive dienophile in asymmetric synthesis of bicyclic adduct through Diels-Alder cycloaddition reaction. |
