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.
