✦ Synopsis

Abstract

The biosynthesis of the benzo[c]phenanthridine alkaloids was investigated in a cell suspension culture of Macleaya cordata (papaveraceae). Feeding experiments define the biosynthetic pathway (–)‐7,8,13,13a‐tetrahydrocoptisine →(–)‐cis‐N‐methyl‐7,8,13,13a‐tetrahydrocoptisinium salt 15→ protopine (5)→ sanguinarine (1)→ chelirubine (3)→ macarpine (4).

C and in some cases also 15 N chemical shifts of quaternary benzo[c]phenanthridine alkaloids (fagaronine, chelerythrine, chelilutine, chelirubine, nitidine, sanguilutine, sanguinarine, and sanguirubine) were systematically studied by NMR spectroscopy and ab initio calculations. The assignment of sig
