The reaction of hemiacetal 2a, from the sugar derived a,b-unsaturated ester 1a, with N-benzylhydroxylamine hydrochloride in situ generates an N-benzylnitrone as a 1,3-dipole, which spontaneously undergoes diastereo-and regioselective intramolecular nitrone olefin cycloaddition to afford a hydroxy fu
