The Biosynthesis of Secondary Metabolites
It is however, clear, from biosynthetic experiments, that whilst the piperidine rings
of N-methylpelletierine (6.19) and anabasine (6.20) derive from the amino acid
lysine (6.17) those of coniine (6.14) and, most surprisingly, anatabine (6. 7) have
...

Plant Secondary Metabolism
Coniine Although the alkaloids coniine (48) and -y-coniceine (SI) bear a
structural resemblance to the piperidine alkaloids, these compounds are derived
from a polyketide pathway (Fig. 29. 1 7). Lysine is a poor precursor, and early
attempts ...
