title: An intramolecular 1,3-dipolar cycloaddition reaction towards the synthesis of chiral azetidine nucleoside analogues: the D-gluco case.
abstract: The diastereoselective intramolecular 1,3-dipolar cycloaddition reaction of unsaturated nitrones, derived from methyl alpha-D-glucopyranoside with 2-furaldehyde and 2-(benzyloxy)acetaldehyde has been studied In our pevious studies with 2-furaldehyde, the cycloaddition resulted 3 diastereoisomers in a 3:1:1 ratio. In this article, how the number of the possible isomers generated by 1,3-cycloaddition could be reduced from 4 to 1 when 2-(benzyloxy)acetaldehyde was employed as an aldehyde is shown.
