✦ Synopsis

The biosynthesis of piperidine and pyridine alkaloids has been studied extensively. The piperidine ring of the majority of these alkaloids, e.g. anabasine,' N-methyl isopelleteriene2 and seaamine', has been shown to arise from lysine via an unsymmetrical intermediate, 6-amino-2-ketohexanoic acid, ana A'-piperideine.

The 2-alkylpiperidine alkaloids e.g. N-methylisopelleteriene*" and anaferine*, are formed by reaction between A'piperideine and the appropriate 6-keto acid derived from acetate. In this step the terminal carboxylic acid group of the keto acid is lost as carbon
