• 개요

  An oily alkaloid isolated from various species of Ormosia, this hex acyclic base has [α]₅₈₉ -11°C and [α]₄₃₆ - 21.3 . It may be characterized as the perchlorate, colourless prisms from MeOH-Et20, m.p. 23S-7°C; the picrate, light yellow needles from Me2CO-Et20, m.p. 237°C (dec.) and the N-methyl derivative, m.p. 103°C which has [α]₅₈₉ + 5° and [α]₄₃₆+ 19° and gives a methiodide, m.p. 209-211°C. Two of the nitrogen atoms are tertiary, the third being present as an imino group. The original structure has been revised to make the alkaloid the 11-epimer of ormosinine (q.v.).
