An unprecedented organocatalyticenantioselective formal synthesis of bromopyrrole alkaloid natural products is reported. An organocatalytic aza-Michael additionusing pyrroles as the N-centered nucleophile is utilized as the enantioselective step to construct the nitrogen-substituted stereogenic carbon center in bromopyrrole alkaloids in good yield and excellent enantioselectivity. The aza-Michael
