that is widely present in many natural products and pharmaceutical compounds. Herein, we report an amidyl radical-mediated dearomatization for synthesizing a series of pyrroloindolines via N-heterocyclic carbene catalysis. In this organocatalytic process, the Breslow enolate served as both a single electron donor and an acyl radical equivalent to assemble C3a-acyl pyrroloindolines with a broad substrate
吡咯并吲哚啉是一种独特的杂环基序,广泛存在于许多天然产物和药物化合物中。在此,我们报道了一种酰胺基介导的脱芳构化作用,通过 N-杂环卡宾催化合成一系列吡咯并吲哚啉。在此有机催化过程中,Breslow 烯醇化物既作为单一电子供体,又作为酰基自由基,在广泛的底物范围内组装 C3a-酰基吡咯并吲哚啉。吲哚衍生物的连续还原提供了(±)-脱氧血清素的类似物,其表现出潜在的抗癌活性。
