A novel metal-free [3+2] annulation of ynamides with anthranils provides a facile, flexible, environmentally friendly, and atom-economical route to 2-aminoindoles. This synthetic process proceeds with efficiency, excellent regioselectivity, and wide functional group tolerance under mild conditions. Moreover, the obtained 2-aminoindole products represent a multifunctional platform for the construction of various 2-aminoindolyl frameworks.
一种新型的炔酰胺与邻氨基苯甲酰亚胺的无金属[3+2]环化反应为合成2-氨基吲哚提供了一条简便、灵活、环境友好且原子经济的途径。该合成过程在温和条件下高效进行，具有出色的区域选择性和广泛的官能团耐受性。此外，所得到的2-氨基吲哚产物是构建各种2-氨基吲哚基骨架的多功能平台。
