Modular synthesis of di- and trisubstituted imidazoles from ketones and aldehydes: a route to kinase inhibitors
A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%–85% yield). A three-...

description | A one-pot and modular approach to the synthesis of 2,4(5)-disubstituted imidazoles was developed based on ketone oxidation, employing catalytic HBr and DMSO, followed by imidazole condensation with aldehydes. This methodology afforded twenty-nine disubstituted NH-imidazoles (23%–85% yield). A three-step synthesis of 20 kinase inhibitors was achieved by employing this oxidation–condensation protocol, followed by bromination and Suzuki coupling in the imidazole ring to yield trisubstituted NH-imidazoles (23%–69%, three steps). This approach was also employed in the synthesis of known inhibitor GSK3037619A. |
