Abstract

Abstract Representative diastereomeric, erythritol and threitol polyhydroxylated pyrrolidine imine scaffolds have been rapidly elaborated to diversely functionalized aza-sugars through highly diastereoselective organometallic (RM) additions (R= Me, Et, allyl, hexenyl, Ph, Bn, pMeO-Bn). The yields for these additions have all been substantially enhanced from previously optimised levels (< 58%) for normal additions using a reverse addition ...
