The reaction of 1,4,5-trisubstituted 1H-imidazole-3-oxides 1 with 2,2-bis(trifluoromethyl)ethene-1,1-dicarbonitrile (7, BTF) yielded the corresponding 1,3-dihydro-2H-imidazol-2-ones 10 and 2-(1,3-dihydro-2H-imidazol- 2-vlidene)malononitriles 11, respectiv
Carboxylate protection for the synthesis of 4,5-disubstituted 1-methylimidazoles

Using the carboxylate function as a readily removed blocking group for the 2-position, a regioselective synthesis of diverse 4,5-disubstituted 1-methylimidazoles has been developed starting from 1-methyltribromoimidazole, 5.
