Direct Nucleophilic Difluoromethylation of Aromatic Isoxazoles Activated by Electron-Withdrawing Groups Using (Difluoromethyl)trimethylsilane
The activation of aromatic diaryl isoxazoles with strong electron-withdrawing groups, such as the nitro, triflyl and the phenylsulfonyl groups, at the 4-position has enabled the first regio- and diastereoselective difluoromethylation at the 5-position of isoxazoles by nucleophilic addition using (di...
