An efficient methodology to access a library of 1,2,4,5-tetrasubstituted imidazoles from a broad range of amidines and α,β-unsaturated aldehydes/ketones via a C(sp2)H amination has been developed. This method represents a new and simple way to prepare highly substituted imidazoles from easily available starting materials, inexpensive catalysts, and with good functional group tolerance in good to excellent
已开发出一种有效的方法,可通过C(sp 2)H胺化从广泛的am和α,β-不饱和醛/酮中获得1,2,4,5-四取代的咪唑的文库。该方法代表了一种新的,简单的方法,可以从容易获得的起始原料,廉价的催化剂以及具有良好的官能团耐受性到优异的产率来制备高度取代的咪唑。
