Synthesis of Imidazoles through the Copper-Catalyzed Cross-Cycloaddition between Two Different Isocyanides
摘要:
The copper-catalyzed reaction between two different isocyanides produces the corresponding heteroaromatization products, imidazoles, in good yields. The reaction proceeds most probably through the activation of the sp3 C-H bond in the isocyanides by a copper catalyst, followed by a [3 + 2] cycloaddition between the cuprioisocyanide intermediates and arylisocyanides.

A facile synthesis of imidazoles and tetrazoles via [3+1+1] type cyclization of ClCF2COONa is developed. A diverse array of imidazoles and tetrazoles were obtained in decent yields via isocyanide intermediates. Notably, this is the first example of the cycloaddition of in situ generated isocyanides.
