An efficient synthesis of aldohexose-derived piperidine nitrones: Precursors of piperidine iminosugars

Abstract

D-Glucopyranose-derived and L-idopyranose-derived piperidine nitrones were synthesized in good overall yields through six-step reaction sequence starting from readily available 2,3,4,6-tetra-O-benzyl-D-glucopyranose. The method is efficient and could be general for the synthesis of aldohexose-derived piperidine nitrones which are precursors of piperidine iminosugars. © 1996-2013 MDPI AG (Basel, Switzerland).
