2β-(1-Hydroxy-1-methylethyl)-4-methoxy-2,3-dihydrofuro[2,3-b]quinoline Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
This furoquinoline alkaloid was first isolated from Platydesma campanulata
Mann and subsequently found in Geijera salicifolia Schott. It crystallizes from
C6H6-light petroleum in white needles and has [α]
25D + 43° (CHCl3). The ultraviolet spectrum in EtOH contains several absorption maxima at 229.3, 238.1,
253.5,262.3,272,283,307.2 and 320.5 mJ.l. with a shoulder at 294.5 mil. The
methiodide forms colourless plates from EtOH, m.p. 1 62-4°C and the picrate
has m.p. 107-9°C after softening at 93°C. The optically inactive base, obtained
as prisms from a mixture of MeOH and isopropyl ether, melts at 137 -SoC and
gives a picrate melting over a very wide temperature range from 96-l22°C.
