Abstract: In order to develop an efficient, practical and stereoselective method to access functionalized azasugar derivatives the microwave assisted 1,3-dipolar cycloaddition of azasugar nitrone and acrylates was investigated which afforded a series of novel azasugar derivatives containing an isoxazolindine moiety. The reaction was performed in a sealed microwave reactor at 110 ℃ in the solution of toluene and proceeded efficiently in yields up to 78%—88% within 5—15 min. The structures and configurations of the products were tentatively determined by 1H NMR, 13C NMR, 2D NMR and HRMS spectral analyses with comparison to the reported X-ray single crystallographic structure of the product 4d-1.
