Stereoselective Intramolecular Oxime Olefin Cycloadditions Involving Carbohydrate Derived Precursors

Intramolecular oxime olefin cycloaddition reactions of carbohydrate derived precursors can be used to prepare highly functionalised 3-oxa-2-azabicyclo[3.3.0]hexanes with good to excellent levels of stereocontrol.
