We report the synthesis of the novel scaffolds pyrazino[1,2-b]isoquinoline and pyrrolo[1,2-a]pyrazine displaying the somatostatin pharmacophores. Both classes of compounds contain a pyrazine heterocycle, which can be prepared in a straightforward manner utilizing an intramolecular Fukuyama-Mitsunobu reaction. As both the families derive from amino acids, they can be accessed in high optical purity
我们报告了新颖的支架吡唑并[1,2-b]异喹啉和吡咯并[1,2-a]吡嗪的合成,显示了生长抑素药效团。这两类化合物均包含吡嗪杂环,其可以利用分子内福山-光延反应以直接方式制备。由于两个家族均来自氨基酸,因此可以高光学纯度获得它们。
