Cycloaddition of Nitrones and Nitrile Oxides to Activated Exo-glycals
The 3+2 cycloaddition reaction of nitrones and nitrile oxides with activated exo-glycals obtained from the Wittig reaction of sugar lactones gave good yields of only two cycloadducts. The reaction was efficiently carried out under microwave activation.
