A one-pot protocol for the construction of fluoroalkylated isoxazoles directly from commercially available amines and alkynes is described. The reaction is scalable, operationally simple, regioselective, mild, and tolerant of a broad range of functional groups. As such, it could be viewed as a “click synthesis” of fluoroalkylated isoxazoles. Preliminary mechanistic investigations reveal that the transformation
描述了一种直接从市售胺和炔烃构建氟代烷基化异恶唑的一锅法操作规程。该反应是可扩展的,操作简单的,区域选择性的,温和的,并且耐受多种官能团。因此,可以将其视为氟代烷基化异恶唑的“点击合成”。初步的机械研究表明,该转化涉及涉及R f CHN 2的空前的Cu催化级联序列。
