Guillou, Sandrine published the artcileSimple preparations of 4 and 5-iodinated pyrazoles as useful building blocks, Recommanded Product: 4-Iodo-3-(trifluoromethyl)-1H-pyrazole, the publication is Tetrahedron (2011), 67(44), 8451-8457, database is CAplus.
The pyrazole nucleus has recently become a recurrent scaffold in the research fields of CropScience and oncol. We report here the preparation of an array of 4- and 5-iodinated pyrazole derivatives, such as 4-iodo-3-trifluoromethylpyrazole or Et 5-iodo-4-carboxy-3-trifluoromethylpyrazoles. This work provide access to many new pyrazole derivative, including eleven original out of sixteen iodinated building blocks, thus opening accesses to new chem. entities featuring a pyrazole nucleus.
Tetrahedron published new progress about 866638-72-4. 866638-72-4 belongs to iodides-buliding-blocks, auxiliary class Trifluoromethyl,Pyrazole,Fluoride,Iodide, name is 4-Iodo-3-(trifluoromethyl)-1H-pyrazole, and the molecular formula is C4H2F3IN2, Recommanded Product: 4-Iodo-3-(trifluoromethyl)-1H-pyrazole.
