[(9S,11S,15S)-17,23-dihydroxy-3-methoxy-25-azatetracyclo[18.3.1.12,6.111,15]hexacosa-1(23),2,4,6(26),20(24),21-hexaen-9-yl] acetate

BeschreibungA non-crystallizable alkaloid isolated from Lythrum anceps Mak., the base yields a very hygroscopic hydrochloride and the O,O-diacetate, the latter giving a crystalline hydrochloride, m.p. 180-218°C (dec.); [α]25D - 33°. When hydrolyzedwith dilute alkalies, the alkaloid gives Lythranidine (q.v.) while treatment with formaldehyde yields Lythamine. Dehydrogenation with Pd-C followed by oxidiation with KMn04 furnishes dipicolinic acid.
