isoprene-catalysed lithiation of different 1-substituted imidazoles (1) (such as trityl, allyl, benzyl, vinyl, N,N-dimethylsulfamoyl, para-toluenesulfonyl, tert-butoxycarbonyl, acetyl, trimethylsilyl, tert-butyldimethylsilyl derivatives) leads to the cleavage of the protectinggroup producing 1H-imidazole. The use of 1-(diethoxymethyl)imidazole (3) in the same lithiation reaction allows the preparation
