4,7-ジヒドロキシ[1,3]ジオキソロ[4,5-j]フェナントリジン-6(5H)-オン 化学特性,用途語,生産方法
説明
The fresh bulbs of many species of Narcissus yield this alkaloid, together with
the preceding base. It resembles narciclasine in that although the structure is
clearly related to those of the Amaryllidaceous alkaloids it shows no basic
properties since the nitrogen is amidic in character. The ultraviolet spectrum in
EtOH is quite complex having absorption maxima at 233, 257, 274, 295, 322,
337 and 353 mil. It contains a methylenedioxy group and two phenolic hydroxyl
groups and furnishes the diacetate which crystallizes from MeOH with m.p.
247°C. The corresponding dimethyl ether is amorphous with melting point
above 320°C.
