  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.

  Selective intramolecular C—H amination via metalloradical activation of azides: synthesis of 1,3-diamines under neutral and nonoxidative conditions. One aspect of the present invention is the synthesis of 1,3-diamines by intramolecular C—H amination of sulfamoyl azides. More specifically, sulfamoyl azides may be selectively aminated via metalloradical activation of azides, preferably with Co(II) porphyrins. In a particularly preferred embodiment, the Co(II) porphyrin is a D 2h -symmetric porphyrin.

  通过金属自由基活化叠氮化合物的选择性分子内C—H胺化：在中性和非氧化条件下合成1,3-二胺。本发明的一个方面是通过叠氮磺酰胺的分子内C—H胺化合成1,3-二胺。更具体地说，叠氮磺酰胺可以通过金属自由基活化叠氮化合物进行选择性胺化，最好使用Co(II)卟啉。在一个特别优选实施例中，Co(II)卟啉是一个D2h对称的卟啉。

  (1) catalyzes the reaction of secondary amides with hydrosilanes, yielding a mixture of secondary amines, tertiary amines, and silyl enamines. Production of secondary amines with complete selectivity is achieved by the use of higher concentration of the catalyst (3 mol %) and the use of bifunctional hydrosilanes such as 1,1,3,3-tetramethyldisiloxane. Acidic workup of the reaction mixture affords the

  甲羰基三钌簇，（μ 3，η 2，η 3，η 5 -acenaphthylene）的Ru 3（CO）7（1）催化仲酰胺与氢硅烷的反应，生成仲胺，叔胺和甲硅烷基烯胺的混合物。通过使用较高浓度的催化剂（3 mol％）和使用双官能氢硅烷（例如1,1,3,3-四甲基二硅氧烷），可以实现具有完全选择性的仲胺的生产。对反应混合物进行酸性处理后，可得到相应的铵盐，可用碱进行处理，从而为分离高纯度仲胺提供了一种简便的方法。相反，通过使用较低浓度的催化剂（1mol％）和聚合氢硅氧烷（PMHS）作为还原剂，以高选择性形成叔胺。用PMHS还原将钌催化剂和有机副产物封装到不溶性有机硅树脂中。这两个反应歧管适用于各种仲酰胺，并且实用性在于该程序提供所需的仲胺或叔胺作为单一产物。产品仅被少量的钌和硅残留物污染。基于产物和观察到的副产物以及NMR研究，还描述了反应的机理方案。
