Here, we disclose an iron(ii)-catalyzed I-O bond cleavage of Koser's hypervalent iodine reagents (HIRs) that initiated the radical cyclization of unsaturated oximes at room temperature. This strategy is successfully applied for the construction of the isoxazoline backbone in an efficient manner. In particular, the direct introduction of a TsO group into products facilitates their late-stage transformations
在这里,我们公开了Koser的高价碘试剂(HIR)的铁(ii)催化IO键裂解,该试剂在室温下引发了不饱和肟的自由基环化反应。该策略已成功地有效地用于异恶唑啉骨架的构建。特别地,将TsO基团直接引入产物中促进了它们在有机合成中的后期转化。
