Herein, we report a highly modular strategy to access spirocyclic scaffolds from abundant starting materials, i.e., cyclic ketones and α-amino or oxamic acids. The sequence proceeds through a straightforward Knoevenagel condensation, followed by a domino Giese-type reaction/base-mediated cyclization process, to deliver a broad scope of polar spirocyclic scaffolds in good to excellent yields. The products
在此,我们报告了一种高度模块化的策略,可以从丰富的起始材料(即环酮和 α-氨基或草酸)中获取螺环支架。该序列通过直接的 Knoevenagel 缩合进行,然后是多米诺 Giese 型反应/碱基介导的环化过程,以良好到极好的收率提供范围广泛的极性螺环支架。产品可以很容易地多样化,从而增加我们方法的通用性,以快速访问潜在的类药物分子库。
