Abstract

Abstract SN 2′ sequences have been employed for the synthesis of β-branched α-amino acids using 1, 2-diastereocontrol for forming C–C bonds. An oxazolidine fragment derived from Garner's aldehyde provides the handle for facial discrimination and acts as a masked amino acid functionality. This study encompasses directed and non-directed allylic substitution reactions. The stereocontrol of the oxazolidine appendage during terminal ...
