Starting from L‐aspartic acid the preparation of 8‐aminopyrido[1,2‐a]indole derivatives as benzo‐fused analogs of the dopamine autoreceptor agonist 1 is reported. The key step of the synthesis is the Tf2O induced cyclization of the 1,2‐amino alcohol 6. Receptor binding studies indicated selective affinity for the D‐2 autoreceptor. Among the tested compounds, the dipropylamino derivative 2 showed the
据报道,从 L-天冬氨酸开始,制备了 8-氨基吡啶并 [1,2-a] 吲哚衍生物,作为多巴胺自身受体激动剂 1 的苯并融合类似物。合成的关键步骤是 Tf2O 诱导的 1,2-氨基醇 6 环化。受体结合研究表明对 D-2 自身受体具有选择性亲和力。在测试的化合物中,二丙氨基衍生物2对选择性自身受体激动剂普拉克索标记的D-2受体显示出最高的亲和力(IC50值:450 nM)。因此,2 的效力比氨基茚1 的效力低 15 倍。
