With microwave irradiation, the efficiency of the 1,3-dipolar cycloaddition of exo-glucal (1) with nitrones 2 was remarkably improved, and the yield of the microwave assisted reaction in a seamless pressure vial at 200 ℃ for 2 min could be up to 96%, providing a practical and convenient method for preparing spiro-isoxazolidine glycosides which are very important intermediates for synthesizing various C-glycosides possessing functional groups.
