What is I~METHOXYDIHYDROCORYNANTHEOL?

Description

This alkaloid has been isolated from Aspidosperma discolor A. DC. and also from the bark of an unnamed species of Aspidosperma (No. RDJ 119070), registered in the Rio de Janeiro Botanical Gardens. The alkaloid may be purified by sublimation or recrystallization from MeOH when it forms colourless crystals. It has [α]²⁴_D - 16.3° (c 1.55, pyridine) or [α]²³_D - 104° (c 1048, CHC13). The ultraviolet spectrum shows absorption maxima at 227 and 280 mil with an inflexion at 293 mil. The base may be characterized as the picrate, yellow needles from aqueous MeOH, m.p. 145-7°C (dec.). The above structure has been proved by synthesis.
