The challenging transamidation of unactivated tertiary amides using equivalent amounts of amines has been accomplished via cooperative acid/iodide catalysis. The method provides a novel manifold to re-route the reactivity of unactivated and unreactive N,N-dialkyl amides through reactive acyl iodide intermediates, representing a powerful new activation mode of unactivated amide bonds.
使用等量的胺对未活化的叔酰胺进行具有挑战性的转酰胺化反应是通过协同酸/碘化物催化完成的。该方法提供了一种新的方法,通过反应性酰碘中间体重新引导未活化和未反应性N,N-二烷基酰胺的反应性,代表了一种强大的未活化酰胺键的新活化模式。
