For today, I would like to advise you to read a very interesting review from Shin Kamijo and Yoshinori Yamamoto on the recent progress in catalytic synthesis of imidazoles. This review has been published recently in Chemistry an Asian Journal, and shows different catalytic methodologies, mainly involving transition metal chemistry but also organocatalytic to synthesisze this very useful heterocyclic ring. For people who cannot have this paper, stay on-line I will show you some examples very soon.
