Cheap and commercially available trichloroisocyanuric acid has been used to promote trifluoromethylation by using TMSCF3 as the trifluoromethyl source. The method provides a novel and efficient protocol for the construction of CF3-containing 4,5-dihydroisoxazoles from allylic oximes in good to excellent yields.
通过使用TMCSF 3作为三氟甲基源,已经使用廉价且可商购的三氯异氰尿酸来促进三氟甲基化。该方法为从烯丙基肟构建具有CF 3的4,5-二氢异恶唑提供了新颖且有效的方案,产率高至优异。
