“…This occurs when there is no oxygenated function at C(1) (Przybylska, 1976); when the protonated N and the oxygenated function are on opposite sides of the ring as in (+)-de(oxymethylene)-lycoctonine hydroiodide hydrate (Przybylska, 1961); and might be expected when the boat form is destabilized by a substituents at C(1) and C(3). It is interesting to note that jesaconitine (Pelletier, DeCamp, Finer-Moore & Ichinohe, 1979) and aconitine (Codding, 1981)both have methoxy and hydroxyl groups at positions C(1) and C(3) respectively. However, jesaconitine crystallized as the perchlorate has a boat configuration while aconitine, as the free base, has a chair.…”
