    Abstract

    Eight new aminomannoglycerolipids (2a-h) with linear, branched, or aromatic acyl chains were synthesized and evaluated for their anti-influenza A virus (IAV) activity. By comparing six mannosyl donors with different protecting and leaving groups, the critical glycosylation reaction employed mannosyl trichloroacetimidate with 2-O-benzoyl protecting group as the donor to give the glycoside with absolute α-anomeric selectivity. The bioactivity results showed that the branched compound 2g could effectively inhibit IAV multiplication in MDCK cells with IC50 69.9μM.
