  Structure-affinity relationships of berbines or 5,6,13,13a-tetrahydro-8H-dibenzo[a,g]quinolizines at α-adrenoceptors

  摘要：

  The synthesis of some derivatives of tetrahydro-8H-dibenzo[a,g]quinolizines or berbines is described. A pharmacological study was carried out at alpha-1 and alpha-2-adrenoceptors using radioligand binding techniques. This study has shown that the aromatic ring A is responsible for the alpha-2-affinity of berbines. Furthermore, the aromatic ring D is important for alpha-1-affinity. However, in this case, it seems that the planarity of the molecule is a very important structural parameter for affinity. The role of the nitrogen atom is also discussed. A conformational analysis of the partial saturated berbines was established by a C-13 NMR study.

  摘要：

  已经开发了一种温和有效的方法，用于通过微波辅助环化N -2-（1'-环己烯基）乙基-乙酰胺/苯甲酰胺来合成spiro-1,3-恶嗪衍生物。原位生成的三甲基甲硅烷基碘化物可催化该反应，其反应时间非常短。通过使取代的乙酸/苯甲酸与2-（1'-环己烯基）乙胺缩合，可以容易地获得起始原料。

  developed for the synthesis of spiro-1,3-oxazine derivatives by the microwave assisted cyclization of N-2-(1′-cyclohexenyl)ethyl-acetamides/benzamides. The reaction was catalyzed by in situ generated trimethylsilyl iodide and featured by its very short reaction time. The starting materials were easily obtained by the condensation of substituted acetic/benzoic acids with 2-(1′-cyclohexenyl)ethyl amine.
