摘要：
An efficient photocatalyst-free visible light enabled synthesis of substituted pyrroles from alpha-keto vinyl azides (readily prepared via Knoevenagel condensation of phenacyl azides with 2-oxo-2H-chromene-3-carbaldehydes) was developed. The reaction proceeds through a denitrogenative photodecomposition of alpha-keto vinyl azides, 1,3-amino group migration, and coupling of intermediates with secondary amines.
