Zhang, Xin-Ke published the artcileIodine-catalyzed oxidative annulation: facile synthesis of pyrazolooxepinopyrazolones via methyl azaarene sp3 C-H functionalization, Synthetic Route of 14580-22-4, the publication is Organic & Biomolecular Chemistry (2022), 20(6), 1236-1242, database is CAplus and MEDLINE.
An iodine-catalyzed Me azaarene sp3 C-H functionalization has been developed for the synthesis of a seven-membered O-heterocyclic architecture containing three different heterocyclic aromatic hydrocarbons. This method can be applied to a wide range of substituted Me azaarenes and diverse 2,4-dihydro-3H-pyrazol-3-ones, and brings about the efficient preparation of 2,9-dihydrooxepino[2,3-c:6,5-c’]dipyrazol-3(7H)-ones in high yields with the merits of low catalyst loading, good functional group tolerance and metal-free conditions.
Organic & Biomolecular Chemistry published new progress about 14580-22-4. 14580-22-4 belongs to pyrazoles-derivatives, auxiliary class Organic Pigment, name is 1-(2-Chlorophenyl)-3-methyl-5-pyrazolone, and the molecular formula is C7H10BNO3, Synthetic Route of 14580-22-4.
