Abstract
Herein, we report an efficient and facile synthesis of substituted 2-aminopyrroles from the reaction of enaminone–amidine adduct and various phenacyl, benzyl, or heteroalkyl halides in the presence of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) in good to excellent yields. The reaction proceeds through an intramolecular 5-exo trig cyclization resulting into diversely substituted 2-aminopyrroles.
