Synthesis of 2-Keto-imidazoles Utilizing N-Arylamino-Substituted N-Heterocyclic Carbenes
摘要:
A new method for the synthesis of 2-aroyl-, 2-heteroaroyl-, and 2-cinnamoyl-substituted imidazoles in very good yields has been developed. The reaction employs novel nitrogen heterocyclic carbenes (NHCs), namely, N-arylamino-substituted NHCs, formed in situ from the corresponding imidazolium salts, and subsequent reaction with aromatic, heteroaromatic, and cinnamic aldehydes without utilizing transition metals or expensive specialized catalysts.

The synthesis of a series of N-aminoimidazoles (NAIMs) with an uncommon spectrum of antiretroviral activity is described. From a group of 60 closely related molecules, we were able to subdivide the molecules in different groups based on their anti-HIV and anti-SIV activity in vitro (i) molecules acting on a new, immediate postintegration step, (ii) molecules acting on both postintegration and HIV-1 reverse transcriptase (RT) as NNRTI, and (iii) molecules that mainly act at the HIV-1 RT according to an NNRTI-type mode of action.
