1,3-Dipolar cycloaddition of D-glucose-derived azomethine ylides for the synthesis of chiral pyrrolidines accompanied an unexpected 1,2-elimination in the furanose moiety of the products. The C3 0 alkoxy/ hydroxy group of the furanose moiety was invariably eliminated under the reaction conditions. A
