The syntheses of an important class of enantiopure five‐membered glyconjucates containing furan unit are described. The regioselective synthesis of a series of sugar‐fused pyrazole heterocycles was achieved by the Huisgen cyclization of aryl diazomethanes with propargyl O ‐glycoside derivatives in good yields. The cycloaddition regioselectivity was confirmed by NMR.
