Intramolecular [3+2] nitrilimine cycloaddition reactions on carbohydrate-derived substrates proceed in a regioselective fashion, affording structurally novel chiral glycopyrazoles (4-6 and 10a-c) in good yields. The products can be subsequently transformed to bicyclic pyrazoles (viz. 11 from 4) or nucleoside analogues (viz. 12 from 4).
