    摘要: The invention relates to a new process for preparing novel racemic and optically active 9- or 11-nitroapovincaminic acid derivatives of the general formula (I) ##STR1## wherein R stands for a --CO--X group, wherein X means a halogen atom; orfor a --CO--OR.sup.1 group, wherein R.sup.1 means an optionally mono- or polysubstituted C.sub.1-10 aliphatic group, a C.sub.3-8 alicyclic group or an aromatic C.sub.6-14 hydrocarbyl group; orfor a --CO--NR.sup.2 R.sup.3 group, wherein R.sup.2 and R.sup.3 are the same or different and stand for a hydrogen atom or a C.sub.1-8 alkyl group optionally forming a saturated heterocycle together with the adjacent nitrogen atom and optionally with one or more further nitrogen atoms or other heteroatoms, and R.sup.3 may also represent an amino group when R.sup.2 stands for a hydrogen atom; orfor a cyano group,as well as their salts and pharmaceutical preparations containing these compounds. Furthermore the invention relates to a process for preparing these compounds and preparations.The racemic and optically active substances of the general formula (I) as well as their pharmaceutically acceptable acid addition and quaternary salts have valuable therapeutic properties, namely vasodilating, spasmolytic, antihypoxic and anticonvulsive effects.
