Lythraceous alkaloids. Part III. Synthesis of the product of dehydrogenation of dideoxy-NO-dimethyl-lythranidine; the structure of lythranidine
Abstract
A seventeen-membered heterocycle (VI), made from anisaldehyde by an eight-step synthesis, was shown to be identical with the product of dehydrogenation of dideoxy-NO-dimethyl-lythranidine. Lythranidine, a novel alkaloid from Lythrum anceps Makino, was thus assigned the structure (XV).
