A step‐economic strategy for 3‐aminoindoles synthesis with ammonia or primaryamines as “N” source under transition‐metal‐free conditions was achieved. A series of 3‐aminoindoles was obtained with abundant “N” source featuring high efficiency, mild conditions, environmental friendliness and scalability. Efficient syntheses of the intermediates of COX‐2 inhibitor and tubulin polymerization inhibitor
