InCl3·3H2O was found to be a mild and effective catalyst for the efficient, one-pot, three component synthesis of 2,4,5-trisubstituted imidazoles at room temperature. Moreover, the utility of this protocol was further explored conveniently for the one-pot, four component synthesis of 1,2,4,5-tetrasubstituted imidazoles in high yields.
发现InCl 3 ·3H 2 O是在室温下高效,一锅,三组分合成2,4,5-三取代的咪唑的温和有效的催化剂。此外,可以方便地进一步探索该方案的实用性,以高产率一锅,四组分合成1,2,4,5-四取代的咪唑。
