✦ Synopsis

Abstract

The commonly accepted structure of γ‐coniceine, the major alkaloid of Conium maculatum L., is revised on the basis of results obtained in the present study with “active hydrogen” determinations and with regard to nuclear magnetic resonance spectra. Infra‐red spectra also support this revision.

γ‐Coniceine is 2‐n‐propyl‐3,4,5,6‐tetrahydropyridine.

The revised structure of γ‐coniceine (a Δ^1^ ‐ piperideine) seems of interest with a view to the biogenesis of the piperidine alkaloids and related amino‐acids.
