  Generation and Trapping of N-Acyliminium Ions Derived from Isomünchnone Cycloadducts. A Versatile Route to Functionalized Heterocycles

  摘要：

  A series of 2-diazo-N-hept-6-enoylmalonamides were prepared and treated with a catalytic amount of rhodium(II) perfluorobutyrate. The resultant carbenoids underwent facile cyclization onto the neighboring amide carbonyl oxygen atom to generate isomunchnone-type intermediates. Subsequent 1,3-dipolar cycloaddition across the pendant olefin afforded intramolecular cycloadducts in high yield. The cascade sequence is simple, direct, and extremely tolerant of structural diversity. Exposure of these cycloadducts to Lewis acids resulted in oxabicyclic ring opening. N-Acyliminium ions of wide structural variety can be easily generated by this sequence of reactions. Different cyclization pathways become available depending on the nature of the substituent group attached to the amide nitrogen. When the tethered group is electrophilic in nature, proton lass from the initially formed N-acyliminium ion occurs rapidly to-give an acyl enamide which undergoes a subsequent cyclization at the electrophilic center.

  醛和胺通过光有机催化活化醛而形成一锅酰胺键

  摘要：

  描述了一种由醛和胺温和，一锅又环保的酰胺合成方法。最初，醛与偶氮二异丙基二异丙酯的光有机催化反应产生中间体羰基酰亚胺，该中间体可与多种胺反应以提供所需的酰胺。各种单取代或双取代醛的初始可见光介导的活化通常很快，发生在几个小时内。在光催化反应之后，在室温下添加伯胺或在高温下添加仲胺导致相应的酰胺从中等收率到优异的收率而没有差向异构化。该方法学被用于合成抗抑郁和社交焦虑症药物莫氯贝胺。

  environmentally friendly synthesis of amides from aldehydes and amines is described. Initially, a photoorganocatalytic reaction of aldehydes with di-isopropyl azodicarboxylate leads to an intermediate carbonyl imide, which can react with a variety of amines to afford the desired amides. The initial visible light-mediated activation of a variety of monosubstituted or disubstituted aldehydes is usually fast,
