convenient synthetic procedures are reported for pyrazole derivatives with carbonyl or ester groups in the 3- and 5-positions and variable substitution pattern at C4 and at the functional side arms. All compounds have been characterized by 1 H and 13 C NMR spectroscopy, elemental analyses, and mass spectrometry. In addition, the structures of several pyrazole derivatives have been determined by single crystal
报告了一系列方便的合成方法,用于在 3 位和 5 位具有羰基或酯基团以及在 C4 和功能性侧臂处具有可变取代模式的吡唑衍生物。所有化合物均已通过 1 H 和 13 C NMR 光谱、元素分析和质谱进行了表征。此外,已经通过单晶 X 射线衍射确定了几种吡唑衍生物的结构,这有助于深入了解功能性侧臂对 NH-吡唑的氢键超分子基序的影响。
