[1R,(+)]-6,6',12'-Trimethoxy-2,2'-dimethyloxyacanthan-7-ol Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
A second bisbenzylisoquinoline base from Limacia cuspidata (Miers.) Hook. f. et
Thorn., the alkaloid is separated from the accompanying !imacine by chromato?
graphy on a silica column. It crystallizes in colourless prisms from MeOH-Me2 CO
and has [α]
D + 110° (CHCI3). One hydroxyl group is present and the alkaloid
yields the O-methyl ether as colourless needles, m.p. 210-2° C; [α]
D + 90°,
(CHCI3), shown to be identical with N-methyl-dihydroepistephanine B. The
structure has been established by chemical interconversions with limacine and
cuspidaline (q.v.).
