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.
我们在此报告了新的 6(5)-bromo-5(6)-methylimidazo[1,2-a]imidazolin-2-ones 的合成途径。通过 Suzuki-Miyaura 交叉偶联反应取代溴,证明了这些支架的合成潜力。可以很容易地引入一大类硼酸(芳基、杂芳基或乙烯基),从而可以访问大量多样化的 6(5)-取代 5(6)-甲基咪唑并[1,2-a]咪唑啉-2-那些。
