Abstract
Process for preparing new derivatives of pentacyclic alkaloids of formula i ** (see formula) ** The hydrogen atom being in position 3 and the ethyl radical in position 16 cis with respect to each other, the hydrogen atom and the hydroxyl radical in position 14 being able to take one or other of the possible orientations, to which isomers a and b, said products of formula i being in their racemic or optically active forms, as well as the salts of said products of formula i with mineral or organic acids, a process characterized by treating a product of formula ii ** (see formula) ** The hydrogen atom being in position 3 and the ethyl radical in position 16 cis with respect to each other, with a reducing agent, obtaining the epimer a or the epimer b of formula i, or its mixture, and treating the reaction product, if desired, with a mineral or organic acid to form the salt.
