A green and ecofriendly enantioselective α‐bromination of carbonyl and 1,3‐dicarbonyl compounds is reported involving the synthesis of a novel organicbrominating source. The organicbrominatingreagent can be recovered after each cycle, rebrominated and reused. The reaction is catalysed by chiralaminoacids and completed within a short reaction time with good enantioselectivity and exclusive formation
