Abstract
(+-)14,15-Dihydro (3beta,14alpha,16alpha) 20,21-dinoreburnamenine-14 -ol (I) is prepd. by treating (+-)3beta, 16alpha-eburnamenine (II) to a heterogeneous phase oxidn-redn. reaction using hydrogen peroxide and a quat. ammonium reducing salt, such as tetrabutyl ammonium borohydride, in the presence of ethyl bromide. The solvent is a mixt. of dichloromethane and 20% aqs. sodium hydroxide, and the reaction is effected at 20 deg. C for 24 hrs. with vigorous stirring. The reaction is hydrolysed progressively and purified by chromatography.
