A simple and rapid access to a variety of 4(5)-arylated imidazoles via palladium-catalyzed Suzuki–Miyaura cross-coupling reaction is described. Coupling parameters were screened for efficient C-4 arylation of N-unprotected 4-iodoimidazole with a broad range of boronic acids under microwave irradiation. Twenty-one imidazole derivatives were synthesized in modest to excellent yields in short reaction

a novel strategy for the treatment of congestive heart failure and myocardial fibrosis. In this study the synthesis and biological evaluation of heteroaryl-substituted naphthalenes and quinolines (1-31) is described. Key step for the preparation of the compounds was a Suzuki cross-coupling. Activity of the compounds was determined in vitro using human CYP11B2 and selectivity was evaluated toward the

be efficiently and selectively prepared by PdCl2(dppf)-catalyzed Suzuki−Miyaura reaction of commercially available 4(5)-bromo-1H-imidazole with arylboronic acids under phase-transfer conditions. On the other hand, N-unprotected 4(5)-aryl-1H-imidazoles can undergo highly selective Pd(OAc)2-catalyzed and CuI-mediated direct C-2-arylation with a variety of aryl bromides and iodidesunderbase-free and
