Alkaloids of Hovea linearis R.Br. The isolation of Ormosia group alkaloids

Abstract

(+)-Sparteine, (–)-N-methylcytisine, (–)-anagyrine, (–)-baptifoline, (±)-piptanthine and (–)-16-epiormosanine have been isolated as alkaloids of H. linearis R.Br. The absolute configuration of (–)-16-epiormosanine has been established by its formation as an hydrogenation product of the alkaloid (–)-podopetaline. Another minor alkaloid may be a new isomer of ormosanine.
