Erybidine (mp 178-180°) is a new alkaloid which has been isolated from the leaves of Erythrina X bidwilli LINDL. (Leguminosae) along with three known Erythrina alkaloids, erythraline (I), erysodine (II), and erythrinine (IV). O-Methylerybidine was proved to be identical with 2, 3, 11, 12-tetramethoxydibenz [d, f] azonine (VI), which was derived from erysodienone (IX). The structure of erybidine (V) was established by the synthesis of this alkaloid from erysodienol (XII). From the viewpoint of biosynthesis, it is interesting that the presence of the dibenz-[d, f] azonine-type base, which was postulated as one of the intermediates of Erythrina alkaloids biosynthesis, was proved, in addition to some erythrinan-type bases.
