The invention relates to a novel process for the manufacture of substituted enantiopure 10hydroxy-dihydrodibenz[b,f]azepines (la), (lb) wherein each of R1 and R2, independently, are hydrogen, halogen, amino or nitro; and each of R3 and R4, independently, are hydrogen or C1-C6alkyl; by transfer hydrogenation of 10-oxo-dihydrodibenz[b,f]azepines; and to novel catalysts of formula (III'a) and (III'b) wherein M is Ru, Rh, Ir, Fe, Co or Ni; L1 is hydrogen; L2 represents an aryl or aryl-aliphatic residue; and the further radicals have the meanings as defined herein; and to new crystal forms of both enantiomers of 10,11-dihydro-10 hydroxy-5Hdibenz[b,f]azepine-5-carboxamide, obtainable by the new processes, their usage in the production of pharmaceutical preparations, new pharmaceutical preparations comprising these new crystal forms and/or the use of these new crystal forms in the treatment of disorders such as epilepsy, or in the production of pharmaceutical formulations which are suitable for this treatment.
该发明涉及一种新型工艺,用于制备取代的对映纯10-羟基-二氢二苯并[b,f]氮杂环己烯(la)、(lb),其中R1和R2中的每一个独立地是氢、卤素、氨基或硝基;R3和R4中的每一个独立地是氢或C1-C6烷基;通过对10-氧代二氢二苯并[b,f]氮杂环己烯的转移氢化;以及新型催化剂的公式(III'a)和(III'b),其中M为Ru、Rh、Ir、Fe、Co或Ni;L1为氢;L2代表芳基或芳基-脂肪残基;以及进一步的基团具有本文中定义的含义;以及通过新工艺获得的10,11-二氢-10-羟基-5H-二苯并[b,f]氮杂环己烯-5-羧酰胺的两个对映体的新晶型,其在制药制剂的生产中的用途,包括这些新晶型的新药物制剂以及这些新晶型在治疗癫痫等疾病或用于制备适用于该治疗的药物配方中的用途。
