There was very little research on the synthesis of β-3-Deoxy-D-manno-oct-2-ulosonic acid (Kdo) C-glycosides, which restricted their wide applications. Herein, a convenient and efficient approach to synthesize β-Kdo C-glycosides was developedbased on Tf2O/(p-Tol)2SO preactivation strategy using bench stable peracetylated Kdo thioglycoside as donor via a thermodynamic SN1-like mechanism.
