Quinozilidine alkaloids

Another example of this useful domino process is the enantioselective synthesis of the quinozilidine alkaloid (-)-lasubine II [234]. Condensed tricyclic compounds as 6/3-28 can also be prepared from norbomene derivatives 6/3-27 in excellent yield, as shown by Funel and coworkers (Scheme 6/3.6) [235]. 

Kasturi (1963) has presented some infrared data concerning alkaloids. Among the compounds were quinozilidine alkaloids, methyl neoreserpate, 3-epialloyo-himbone, and 3-epialloyohimbine (conformational data). Other compounds mentioned were the tobacco alkaloid myosmine the substances histisine, angustifoline, recanescine, and reserpine other Rauwolfia alkaloids some Vinca alkaloids and powellane. Neuss (1959) has also supplied data on indole and dihydroindole alkaloids.
