O’Sullivan, Leonie published the artcileRegioselective Synthesis of C3-Hydroxyarylated Pyrazoles, Safety of 1-Methylpyrazole, the publication is Journal of Organic Chemistry (2022), 87(1), 846-854, database is CAplus and MEDLINE.
The first regioselective route to C3-hydroxyarylated pyrazoles obtained through reaction of pyrazole N-oxides with arynes using mild conditions is reported. Importantly, this method does not require the C4 and C5 positions of the pyrazole to be functionalized to observe regioselectivity. Using this method, authors completed the synthesis of a recently reported JAK 1/2 inhibitor. Authors’ synthesis produces the desired product in 4 steps from com. available starting materials.
Journal of Organic Chemistry published new progress about 930-36-9. 930-36-9 belongs to pyrazoles-derivatives, auxiliary class Pyrazole, name is 1-Methylpyrazole, and the molecular formula is C4H6N2, Safety of 1-Methylpyrazole.
