Upon treatment of fructose-derived nitrone 1 with samariumdiiodide, with the aim of inducing its umpolung and coupling with electrophiles, an unexpected β-elimination of the benzyloxy group at C-1 was observed, yielding nitrone 2. The mechanism and scope of this transformation were investigated, from nitrone 1 and from five other α-alkoxy or α-acyloxy nitrones. This paper describes the preparation
