the totalsynthesis of (2S,3R)-3-hydroxypipecolicacid (−)-1a and (2R,3R)-3-hydroxy-2-hydroxymethylpiperidine (−)-2a is reported. The synthetic pathway involves conversion of d-glucose into 3-azidopentodialdose (5) followed by the Wittig olefination and reduction to give the piperidine ring skeleton (8) with a sugar appendage that on cleavage of an anomeric carbon followed by oxidation gives (−)-1a
