Regio-specific and non-regiospecific condensation reactions on 1,3-dicarbonyl compounds rendered 1,3,5-trisubstituted pyrazoles. Herein, the control of regio-specificity was a significant improvement in pyrazole research. A high yield acylation of poorly nucleophilic aryl amines, which resulted in mono- or diacylated products depending on the reaction conditions, is described. As a result, a library
在1,3-二羰基化合物上的区域特异性和非区域特异性缩合反应得到1,3,5-三取代的吡唑。在本文中,对区域特异性的控制是吡唑研究中的显着改善。描述了亲核性差的芳基胺的高产率酰化,其取决于反应条件导致单酰化或二酰化的产物。结果,获得了具有潜在生物活性的化合物的文库。
