efficient enantioselective synthesis of natural product (S)-3-hydroxypiperidine has been achieved starting from commercially available raw materials employing two catalytic routes: (i) cocatalyzed hydrolytic kineticresolution (HKR) of racemic methyl-3-(oxiran-2-yl)propanoate; (ii) proline-catalyzed α-aminooxylation followed by Horner–Wardsworth–Emmons olefination in high enantiomericpurity (97% ee)
Chirospecific Synthesis of (<i>S</i>)-(+)- and (<i>R</i>)-(-)-5-Amino-4-hydroxypentanoic Acid from L- and D-Glutamic Acid via (<i>S</i>)-(+)- and (<i>R</i>)-(-)-5-Hydroxy-2-oxopiperidine

5-Hydroxy-2-oxopiperidine, which we earlier prepared from 5-hydroxy-2-pyridene can now be prepared stereospecifically [(S)-(+)- and (R)-(-)isomers] from L- and D-glutamic acid, respectively, by a five-step sequence. Ring cleavage of (S)-(-)-5-hydroxy-2-oxopiperidine with hot aqueous barium hydroxide affords (S)-(+)-5-amino-4-hydroxypentanoic acid, a homolog of the pharmacologically interesting acid GABOB.
