20-Hydroxy-17-methoxyaspidospermidin-21-oic acid methyl ester Chemische Eigenschaften,Einsatz,Produktion Methoden
Beschreibung
An alkaloid isolated from Aspidosperma cylindrocarpon, this base is laevoro·
tatory with a specific rotation of [α]
20D - 300°. In MeOH it gives an ultraviolet
spectrum with absorption maxima at 213, 248 and 290 nm. A number of ester
derivatives have been described including the N·formy1 with an indefinite melting
point; specific rotation of [α]
20D - 250° (c 0.002, MeOH) and an ultraviolet
spectrum with absorption maxima at 219, 259 and 291 nm; the N·acetyl com·
pound, m.p. 207-210°C, forming colourless crystals from MeOH and having
[α]
20D - 400° (c 0.002, MeOH) and an ultraviolet spectrum in MeOH with
absorption maxima at 228, 256 and 289 nm with a shoulder at 281 nm; the
O·xanthate, m.p. 45°C; [α]
20D - 250° (c 0.002, MeOH); the N·benzoyl
derivative, m.p. 215-6°C and [α]
20D - 160° (c 0.0012, MeOH) and the N·
cinnamoyl compound with m.p. 123-4°C and [α]
20D- 384° (c 0.0042, MeOH).
