    摘要: The invention relates to a new process for the preparation of eburnamonine derivatives of the general Formula I ##STR1## (wherein R.sup.1 is an alkyl group having 1-6 carbon atoms) and optical and geometrical isomers thereof which comprises reacting a hydroxyimino-octahydro-indolo[2,3-a]quinolizine derivative of the general Formula II ##STR2## (wherein R.sup.1 is as stated above and R.sup.2 stands for an alkyl group having 1-6 carbon atoms being identical with or different from R.sup.1, or a hydrogen atom) or an acid addition salt thereof in an organic protic solvent or solvent mixture with an inorganic base, optionally under the addition of water or an aqueous mineral acid, at a temperature between 60.degree. C. and 200.degree. C.The compounds of the present invention are known drugs having blood pressure decreasing and cerebral vasodilatatory effect. The advantage of the process of the present invention is that it is readily feasible on industrial scale too, provides isomer-free pure products with high yield and requires the use of readily available simple starting materials.

    摘要: The invention relates to a new process for the preparation of apovincaminic acid esters. More particularly, the invention concerns a process for preparing racemic and optionally active vincaminic acid esters of the formula (I) ##STR1## in which R.sup.1 and R.sup.2 independently stand for alkyl having from one to 6 carbon atoms, and 14-epimers thereof.According to the invention an octahydroindolo[2,3-a]quinolizine-oxime ester of the formula (II) ##STR2## in which R.sup.1 and R.sup.2 have the same meaning as defined above, is reacted with an aqueous solution of sulfurous acid or a salt thereof at a temperature of 80.degree. to 110.degree. C. and the 14-epimeric mixture obtained is epimerized or separated in a known manner and if desired, the racemic vincaminic acid esters are resolved.The valuable, pharmaceutically active compounds of the formula (I) can be prepared according to the invention in a considerably improved yield and the undesired side reactions can be suppressed and/or the by-products can easily be converted into other pharmaceutically active materials.
