ACETOXYLATION OF PIPERIDINE DERIVATIVES AT THE 3-POSITION. STEREOSELECTIVE SYNTHESIS OF PSEUDOCONHYDRINE AND N-METHYLPSEUDOCONHYDRINE

Anodic oxidation of N-methoxycarbonylpiperidine derivatives in AcOH gave 2,3-diacetoxylated products, which were shown to be useful intermediates for the stereoselective synthesis of 3-hydroxypiperidine derivatives including pseudoconhydrine and N-methylpseudoconhydrine, the Conium alkaloids.
