Abstract We report herein a synthetic pathway to new 6 (5)-bromo-5 (6)-methylimidazo [1, 2- a] imidazolin-2-ones. The synthetic potential of these scaffolds was demonstrated by displacing bromine by Suzuki–Miyaura cross-coupling reactions. A large panel of boronic acids (aryl, heteroaryl or vinyl) could easily be introduced, giving access to a large and diversified library of 6 (5)-substituted 5 (6)-methylimidazo [1, 2-a] imidazolin-2-ones.
