A generalized synthesis of α-d-cholesterylglycosides has been achieved using one-pot per-O-trimethylsilyl glycosyl iodide glycosidation. Both cholesteryl α-d-glucopyranoside (αCG) and cholesteryl α-d-galactopyranoside were prepared in high yield. These compounds were further esterified using regioselective enzymatic acylation with tetradecanoyl vinyl ester to afford 6-O-tetradecanoyl-α-d-cholesteryl glucopyranoside (αCAG) of Helicobacter pylori and the corresponding galactose analogue in 66-78% overall yields from free sugars. The tandem step-economy sequence provides novel analogues to facilitate glycolipidomic profiling.
