Zhang, Rong published the artcileIodine-Catalyzed Construction of Dihydrooxepines via 3-Methyl-5-Pyrazolones C-H Oxidation/Functionalization of Quinolines Cascade, COA of Formula: C10H9ClN2O, the publication is European Journal of Organic Chemistry (2021), 2021(27), 3807-3811, database is CAplus.
An efficient iodine-catalyzed [3+3+1] annulation for the construction of dihydrooxepine scaffolds with quinoline units was developed. This strategy involved a seven-membered dihydrooxepine with a broad substrate scope through a formal three-component tandem reaction. Further derivation of the target product produced a trioxabicycle scaffold, which formed the basic core of natural products and pharmaceutical mols.
