A ring-opening fluorination of isoxazoles has been developed. Upon treatment of isoxazoles with an electrophilic fluorinating agent (Selectfluor), fluorination followed by deprotonation leads to tertiary fluorinated carbonyl compounds. This method features mild reaction conditions, good functional group tolerance, and a simple experimental procedure. Diverse transformations of the resulting α-fluorocyanoketones
已经开发了异恶唑的开环氟化。在用亲电子氟化剂 (Selectfluor) 处理异恶唑后,氟化后去质子化产生叔氟化羰基化合物。该方法具有反应条件温和、官能团耐受性好、实验步骤简单等特点。还展示了所得 α-氟氰基酮的多种转化,提供了多种氟化化合物。
