(7R)-6,7,7aβ,8-テトラヒドロ-7-メチル-5H-ベンゾ[g]-1,3-ベンゾジオキソロ[6,5,4-de]キノリン-12-オール7-オキシド 化学特性,用途語,生産方法
説明
The alkaloid originally isolated under this name by Aston proved to be a
mixture of laureline and pukateine and the name was then given to a third alkaloid occurring in the bark of Laurelia Novae-Zelandae. The base crystallizes in
colOUrless needles or hexagonal tablets and is laevorotatory with [α]
D - 222°
(CHCl 3 ). The sulphate hexahydrate, m.p. 99-l00°C is almost completely insoluble in H20; the methiodide has m.p. 249-250°C and the O,G-dimethyl
ether forms colourless prisms, m.p. l34°C, b.p. 200-2l0°C/l0 mm; [α]
D - 314°
(CHC13). The probable structure, given above, has been deduced by comparison
with other, similar alkaloids although the alternative structure 3 :4-dihydroxy-
6:7-methylenedioxyaporphine, is not completely excluded.
