acetylbenzoylaconitine C화학적 특성, 용도, 생산

개요

This alkaloid is generally regarded as being identical with aconitine although it has been considered different by Paul and Kingzett, Dunstan and Read and Makoshi. Schultz and Liebner believed the two bases to be isomerides yieldinghe same pyraconitine. The view that the alkaloids are distinct has been supported by the differences in crystal form found by Pope and Schwankte. For completeness, the description given by Dunstan and Read is given below.
The base forms rosettes of colourless needles and has [α] _D + 20.26° (CHCI3). Several crystalline salts have been prepared, e.g. the hydrochloride trihydrate, m.p. 149-1 50°C; hydrobromide tetrahydrate, m.p. 172-3°C; nitrate, m.p. 173-7°C (194°C); aurichloride occurring in two forms (a) yellow prisms, m.p. 1 54-160°C and yellow rosettes, m.p. 231°C; thiocyanate, m.p. 190-2°e. The methiodide, m.p. 224-SoC furnishes methyljapaconitine, m.p. 206°C with dilute KOH. With AcCl, the base yields the triacetyl derivative, m.p. 166°C. Acid hydrolysis yields acetic acid and japbenzaconine, m.p. 183°C while alkaline hydrolysis gives acetic and benzoic acids and japaconine, m.p. 99-1 OO°C. Pro_x0002_longed heating at the melting point gives pyrojapaconitine, m.p. 167 -8°C identical with pyraconitine.
