Synthesis of cycleanine mono-N-oxides

Oxidation of cycleanine (3) with m-chloroperbenzoic acid gave two diastereomeric N-oxides (1 and 2), and their stereochemistry was unambiguously determined on the basis of spectroscopic evidence. The NMR spectra of synthetic cycleanine mono-N-oxides 1 and 2 were significantly different from those of the natural product previously reported to be cycleanine N-oxide.
THE BIOSYNTHESIS OF THE ALKALOIDS OF CISSAMPELOS PAREIRA LINN

Tracer experimets show that the bisbenzylisoqunoline alkaloid,(S,R)-hayatidin (10) is stereospecifically biosynthesized in young Cissampelos pareira Linn plants by intermolecular oxidativ coupling of (S)-(5)-and (R)-(3)-N-methylcoclaurines whereas (R,R)-isochondrodendrine (14) and (R,R)-bebeerine (12) are formed in the plants by oxidative dimerization of (R)-N-methyl-coclaurine (3).
