An efficient and novel process is described for the asymmetric synthesis of (2S,3S,SR)-1-methyl-5-nonyl-2-(phenylmethyl)-3-pyrrolidinol, (+)-preussin employing reductive deoxygenation of a functionalized quaternary alpha-hydroxy N-Boc pyrrolidine obtained by stereocontrolled elaboration of tri-O-benzyl-beta-D-arabinofuranose. The synthetic strategy involves no separation of stereoisomers through the entire sequence.
