This communication outlines the development of a direct synthetic route to 1,2-dimethyl-3-R-5-salicyloyl-imino-3-pyrazolines, starting from readily available 3(5)-aminopyrazoles 1a, b, c and methyl salicylate. The structures of the new compounds 3a, b, c were determined on the basis of analytical and spectroscopic data as well as on the acid hydrolysis products.
该通报概述了从容易获得的3(5)-氨基吡唑1a,b,c和水杨酸甲酯开始,向1,2-二甲基-3- R -5-水杨酰基-亚氨基-3-吡唑啉直接合成的方法的开发。根据分析和光谱数据以及酸水解产物确定新化合物3a,b,c的结构。
