Electrophilic Iodination of 4-Nitroimidazoles - a New High Yielding Method for the Synthesis of 4-Nitro-5-iodoimidazoles
摘要:
Electrophilic iodination of 4-nitroimidazoles employing the system KI-HN3-AcOH provided for the synthesis of 4-nitro-5-iodoimidazoles in high yields. With 2-unsubstituted-4-nitroimidazoles, 2,5-diiodo-4-nitro-imidazoles were obtained.

N-Methylimidazole has been shown to be a promising catalyst for aza-Michael reactions. Various N-heterocycles were introduced to α,β-unsaturated carbonyl compounds employing N-methylimidazole (0.05 equiv) in a highly efficient, rapid and high yielding synthesis of N-heterocyclic derivatives.
