Abstract
Process for the prepn. of vincamine (I) or 14,15-dehydro-vincamine (apovincamine) by oxidn. and then rearrangement of a soln. of vincadifformine or tabersonine respectively, is characterised in that a protecting agent is added to the starting soln., which is in a polar solvent at a temp. equal to or below 5 deg.C, then the oxidn. is effected with permaleic or peracetic acid, and when addn. of peracid is complete, the rearrangement is effected by heating the reaction mixt. at 20-50 deg.C. The protecting cpd. may be a copper salt, added in quantities such that the ratio of starting cpd. to copper salt is 1-10:1. The protecting agent may also be oxalic acid, which is added to the initial soln. at -5 deg.C, followed by addn. of the peracid at -2 deg.C. The polar solvent used is a lower aliphatic alcohol pref. methanol. The pH after addn. of the peracid is 6-2.5. Permaleic acid may be prepd. in situ from maleic anhydride and hydrogen peroxide. The peracid is added at -5 to 0 deg.C. At the end of the reaction the copper salt is sepd. When permaleic acid is used the precipitated copper salt is filtered off. When peracetic is used, the copper salt may be removed by chelation on a resin, such as a macroporous polystyrene polymer having amino-phosphonic, amino-diacetic or amino-oximic functional gps. The rearrangement is effected by heating at 30-50 deg.C, pref. 35-40 deg.C. Before or during this stage, a reducing agent, such as sodium metabisulphite, sulphur dioxide or sodium, may be added, which aids later purificn. Prepn. of vincamine used for the treatment of cerebrovascular troubles.
