A Cyclic Sulfate Approach to the Synthesis of 1,4-Dideoxy-1,4-imino Derivatives of L-Xylitol, L-Arabinitol and D-Xylitol

Abstract
Polyhydroxylated pyrrolidines are readily accessible by ring opening of a 1,4-cyclic sulfate function in pentitol derivatives by nitrogen nucleophiles and further processing of the in situ generated charged sulfate group.
