A facile route to imidazol-4-yl anions and their reaction with carbonyl compounds
摘要:
Treatment of N-protected 4-iodoimidazoles 1-3 in CH2Cl2 solution with an ethereal solution of ethyl-magnesium bromide generates the corresponding imidazol-4-yl anions, which react with carbonyl compounds to give carbinols 4-14 in 60-83% yield.
