A de novo synthesis of novel polyhydroxylated N-alkoxypiperidines based on the ring-closing double reductive amination of 1,5-dialdehydes, obtained by oxidative cleavage of cyclopentene derivatives, with O-substituted hydroxylamines is reported. Isofagomine was accessed by cleavage of the N–O bond of an N-alkoxypiperidine.
