Direct and rapid construction of carbazoles has been successfully developed via carbene-catalyzed oxidative formal [4 + 2] annulation of enals with 2-methyl-3-oxoacetate indoles. This metal-free reaction features a broad substrate scope, features good functional-group tolerance, proceeds under mild conditions, and can be easily scaled up.
通过卡宾催化2- [3-氧代乙酸甲酯]的烯醛氧化[4 + 2]正环化,已成功开发了直接快速构建咔唑的方法。这种无金属的反应具有广泛的底物范围,具有良好的官能团耐受性,可在温和条件下进行,并且易于扩大规模。
