The iodine‐catalyzed decarboxylative amidation of β,γ‐unsaturated carboxylic acids with chloramine salts is described. This method enables the regioselective synthesis of allylic amides from various types of β,γ‐unsaturated carboxylic acids containing substituents at the α‐ and β‐positions. In the reaction, N‐iodo‐N‐chloroamides, generated by the reaction of a chloramine salt with I2, function as a
描述了碘催化β,γ-不饱和羧酸与氯胺盐的脱羧酰胺化反应。这种方法能够从各种类型的在α和β位置带有取代基的β,γ-不饱和羧酸区域选择性合成烯丙基酰胺。在反应中,氯胺盐与I 2反应生成的N碘N氯酰胺起关键活性物质的作用。该反应为合成有用的仲烯丙基胺衍生物的现有方法提供了有吸引力的替代方法。
