  N-酰基戊二酰亚胺与胺 的氨基转移†

  摘要：

  由于酰胺键在化学的各个领域中起着核心作用，因此开发用于酰胺合成的新的转酰胺基反应是一个重要而活跃的研究领域。在这里，我们报告了一种新的方法，该方法在轻度，无金属的条件下，依靠酰胺键扭曲来弱化酰胺共振，从而使N-酰基-戊二酰亚胺与胺进行氨基转移。在反应条件下可以耐受各种胺和官能团，包括在金属催化方案中会出现问题的亲电取代基。机理实验表明，酰胺键的扭曲，四面体中间体的热力学稳定性以及戊二酰亚胺的离去基团能力是控制该过程反应性的因素。该方法进一步建立了合成的效用。N-酰基-戊二酰胺是通过无金属途径在酰基转移反应中稳定的，扭曲的，垂直于酰胺的酰胺基试剂。讨论并比较了N-酰基戊二酰亚胺在无金属和金属催化过程中的反应性起源。

  diverse amines. Various readily reducible functional groups, such as esters, alkynes, and alkenes, were well tolerated. Furthermore, the methodology was extended to the synthesis of bio- and drug-derived amines. Detailed mechanistic studies revealed a reaction pathway entailing aldehyde and amido complex formation via an unusual C–N bond cleavage-reformation process, followed by C–O bond cleavage.

  Amides are prevalent in organic synthesis. Developing an efficient synthesis that avoids expensive oxidants and heating is highly desirable. Here the oxidative amidation of aromatic aldehydes is reported using an inexpensive metal-free visible light photocatalyst, phenazine ethosulfate, at low catalytic loading (1–2 mol %). The reaction proceeds at ambient temperature and uses air as the sole oxidant

  Heterogeneous photocatalytic organic synthesis is fascinating because of the utilization of ubiquitous solar light for chemical transformations. Here, three Fe-MOFs with different Fe-O clusters, Lewis acid sites and morphologies were synthesized through coordination structure engineering. Pd/Fe-MOFs nanocomposites were used to challenge the amide bond green synthesis with visible light. Pd/MIL-101(Fe)
