AbstractUnsaturated spirocyclic lactams stemming from a variant of the three-component Castagnoli–Cushman reaction successfully underwent hydrogenation to enable access to fully saturated spirocyclic lactams. The subsequent lactam reduction gave rise to 2-spiro piperidine building blocks. The latter can be further elaborated in compound libraries and, on their own, show propensity to activate trace amine-associated receptor 1 (TAAR1), an important target for CNS disease.
摘要源自三组分Castagnoli–Cushman反应变体的不饱和螺环内酰胺成功经过氢化反应,以便访问完全饱和的螺环内酰胺。随后的内酰胺还原产生了2-螺环哌啶构建块。后者可以在化合物库中进一步详细研究,并且本身显示出激活微量胺相关受体1(TAAR1)的倾向,这是中枢神经系统疾病的重要靶点。
