Three complex 7-oxygenated-8-prenylflavones, (-)-semiglabrin and (-)-pseudosemiglabrin, which are diastereoisomers, and lanceolatin A have been isolated from the root of Tephrosia apollinea (Del.) Link (Leguminosae) growing in Southern Egypt, together wit

A general approach to the synthesis of the flavone-furo[2,3-b]furan ring system present in numerous biologically-active secondary metabolites of Tephrosia sp. has been developed and applied in one racemic synthesis and two asymmetric syntheses of four mem

A total of six complex 7-oxygenated-8-prenylflavones have been isolated from the seeds of Tephrosia apollinea and identified as the diastereoisomers (-)-semiglabrin and (-)-pseudosemiglabrin, (+)-glabratephrin, (+)-glabratephrinol, appollinine (7-methoxy-8-[3″-(2″,5″-dihydro-5″,5″-dimethyl-2″-oxofuryl)]-flavone and lanceolatin-A. The use of 13C NMR in the structure elucidation of flavones of this type is discussed. The potential chemotaxonomic value of Tephrosia flavones of the type isolated from T. apollinea is explored.
