Description |
Intramolecular [3C2] 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).
