Abstract A metal-, oxidant-, and additive-free conversion of hydroxamates to esters have been achieved using molecular iodine as the reagent using a novel but not-so-explored heron-type rearrangement. The reaction proceeds with almost equal facility with substrates having either electron-donating or electron-withdrawing substituent. Similarly, α,ß-unsaturated, and sterically hindered ortho-substituted
摘要 使用分子碘作为试剂,使用一种新颖但尚未探索的苍鹭型重排,实现了无金属、无氧化剂和无添加剂的异羟肟酸酯转化为酯。反应以几乎相同的便利与具有给电子或吸电子取代基的底物进行。类似地,α,β-不饱和和空间位阻的邻位取代异羟肟酸酯也能顺利进行所需的转化。图形概要
