Abstract The structure (XXVII) proposed for securinine is confirmed by synthetic structural proof of the key degradation products, lactam-carbinol B (XXIII) and quinolizidine B (XX).

Abstract The absolute configuration of securinine was shown to be I from the rotatory dispersion curves and molecular rotations of degradation products of securinine. The conclusion was unequivocally confirmed by the formation of (+)-N-benzoylpipecolic acid on degradation of this alkaloid. The conformation of the bridgehead nitrogen was also discussed.
