The pyrazole nucleus has recently become a recurrent scaffold in the research fields of CropScience and oncology. We report here the preparation of an array of 4- and 5-iodinated pyrazole derivatives, such as 4-iodo-3-trifluoromethylpyrazole or ethyl 5-iodo-4-carboxy-3-trifluoromethylpyrazoles. This work provide access to many new pyrazole derivative, including 11 original out of 16 iodinated building
吡唑核最近已成为作物科学和肿瘤学研究领域的复发支架。我们在这里报告了一系列4-和5-碘代吡唑衍生物的制备,例如4-碘-3-三氟甲基吡唑或乙基5-碘-4-羧基-3-三氟甲基吡唑。这项工作为人们提供了许多新的吡唑衍生物的途径,包括16种碘化结构单元中的11种,从而为具有吡唑核的新化学实体提供了途径。
