Imines derivedfrom O-protected (S)-glyceraldehyde are valuable intermediates in the synthesis of different kinds of amino acids. We have developed a highly convergent and stereoselective method to obtain (2S,3S)-N-tert-butoxycarbonyl-1-phenyl-3,4-epoxy-2-butylamine and (2S,4R)-N-tert-butoxycarbonyl-4-hydroxypipecolic acid tert-butylamide, which are key intermediates in the synthesis of Palinavir,
