methods have been developed for the reduction of the active substance of the medicinal preparation Dimebon (2,8-dimethyl-5-[2-(6-methylpyrid-3-yl)ethyl]-1,2,3,4-tetrahydro-γ-carboline) to the corresponding racemic cis- and trans-1,2,3,4,4a,9b-hexahydro derivatives, distinguished by a high degree of stereoselectivity. The structures of the obtained diastereomeric hexahydro-γ-carbolines were confirmed
已经开发出用于减少药物制剂Dimebon(2,8-二甲基-5- [2-(6-(6-甲基吡啶-3-基)乙基] -1,2,3,4-四氢-γ-咔啉)形成相应的外消旋顺式和反式1,2,3,4,4a,9b-六氢衍生物,其立体选择性很高。通过各种物理化学方法,包括X射线结构分析,确认了所获得的非对映异构体六氢-γ-咔啉的结构。
