Polyfunctionalisation of imidazole via sequential imidazolyl anion formation
摘要:
A method for achieving the sequential functionalisation of the imidazole ring in the order C-5-->C-4-->C-2 is described. The chemistry proceeds via the regioselective formation of positionally stable imidazolyl anions which are reacted with electrophiles (aldehydes, alkyl halides, azides, formamides, isocyanates) to afford substituted imidazoles in 31-90% yield.
