Pachycarpa

Matrine Group.—A new member of this group, sophorbenzamine, has been isolated from Goebelia pachycarpa and shown to be the benzyl derivative (17) on the basis of spectroscopic studies.7 Sophora moorcroftiana contains the known alkaloids a-matrine, oxymatrine, and sophocarpine.13... [Pg.69]

The synthesis of an analogue, a pyranochalcone isolated from a related species Millettia pachycarpa, which is described (ref.84) as an insect anti-feedant, commenced with the prenylation of 2,4-dihydroxyacetophenone with prenyl bromide in a basic medium to afford several products but primarily 2,4-dihydroxy-3-C-prenylacetophenone in 50% yield. Formic acid cyclisation gave a pyrone which was condensed with anisaldehyde. The resulting chalcone was oxidised in which reaction the non hydrogen-bonded hydroxyl group participated to obtain the final product. This was also be derived by the alternative of chalcone formation from 2,4-dihydroxyacetophenone followed by prenylation (non-specific) and finally DDQ oxidation. [Pg.425]

QuinoiizidLne Alkaloids.—Analysis of Goebelia pachycarpa shoots after administration of " C-labelled matridinc (41) and matrine (42) has indicated the sequence for alkaloid biosynthesis as matridine, matrine, matrine N-oxide, sophocarpine (43), sophocarpine iV-oxide, and sophoramine (44). ...

Matrine-type alkaloids [as (6)] were found to be labelled by radioactive lysine and cadaverine in Goebelia pachycarpa and to be interconvertible. Quinolizidine alkaloids of the sparteine type [as (5)] are known to arise from three molecules of lysine via a symmetrical intermediate (cadaverine). Aphylline (8) also arises from three molecules of lysine in Anabasis aphylla, but without the participation of a symmetrical intermediate. ... [Pg.2]
