Highly diastereoselective synthesis of densely functionalized cyclopentanoids by intramolecular azomethine imine cycloadditions in sugar templates

Conversion of a sugar to a σ,ε-unsaturated aldehyde, and subsequent condensation of the aldehyde moiety with BnNHNHCO2Et, yields the respective azomethine imine intermediate dipole which adds intramolecularly to the existing double bond, thus generating a bicyclic adduct with high diastereoselectivity.
