Visible-Light-Enabled Multicomponent Cascade Transformation from Indoles to 2-Azidoindolin-3-yl 2-Aminobenzoates

摘要

The synthesis of 2-azido-1-benzoylindolin-3-yl 2-benzamidobenzoate commencing from (1H-indol-1-yl)(phenyl)methanone and trimethylsilyl azide (TMSN3) under oxygen atmosphere is described in this paper. This transformation proceeds via a sequential dearomatization and ring-opening cascade reaction of indoles in a cascade manner.
