  Photophysics and Photochemistry of Intramolecular Stilbene-Amine Exciplexes

  摘要：

  The photophysical and photochemical behavior of a series of trans-(aminoalkyl)stilbenes in which a primary, secondary, or tertiary amine is appended to the stilbene ortho position with a methyl, ethyl, or propyl linker has been investigated. The tertiary (aminoalkyl)stilbenes form fluorescent exciplexes and undergo trans-cis isomerization, but fail to undergo intramolecular reactions analogous to intermolecular addition reactions observed for stilbene with tertiary amines. The photophysical behavior of the tertiary (aminoalkyl)stilbenes is dependent upon the choice of linker, solvent, and temperature. The secondary (aminoalkyl)stilbenes do not form fluorescent exciplexes but undergo intramolecular N-H addition to the stilbene double bond. Unlike the intermolecular reactions of substituted stilbenes with secondary amines, which yield mixtures of regioisomeric adducts and reduction products, the intramolecular reactions are highly selective, providing an efficient method for the synthesis of tetrahydrobenzazepines. Direct irradiation of the primary (aminoalkyl)stilbenes results only in trans-cis isomerization. However, irradiation in the presence of the electron acceptor p-dicyanobenzene results in regioselective intramolecular N-H addition to the stilbene double bond. These results are discussed in terms of the mechanisms of direct and electron-transfer-sensitized irradiation.

  describes a novel supported Weinreb amide resin that facilitates parallel synthesis of aldehydes and ketones on a scale useful for chemical library synthesis. This new resin makes it possible to produce custom aldehydes and ketones from a wide range of carboxylic acids, including N-BOC-amino acids. A variety of commercially unavailable aldehydes are easily synthesized in parallel and obtained in high purity

  本文介绍了一种新型的负载型Weinreb酰胺树脂，该树脂有助于以可用于化学库合成的规模并行合成醛和酮。这种新的树脂可以从多种羧酸（包括N-BOC-氨基酸）生产定制的醛和酮。可以轻松地并行合成各种商业上不可用的醛，并通过简单的过滤后处理以高纯度获得这些醛，从而促进了铅优化库的并行合成，该库通常需要定制醛中间体的合成来发展结构-活性关系。为了证明此方法的实用性，我们基于支持的Horner-Emmons试剂合成了一个小型文库。这是首次证明通过担载的Weinreb酰胺产生的醛可直接用作采用对水分敏感的反应的化学文库合成中的试剂。由于必需的费力的萃取后处理程序，有时这些反应性中间体的不稳定性，因此类似的溶液反应不适合于平行合成。

  We here report a study of the intramolecular amination of sp3 C–H bonds via the hydride transfer cyclization of N-tosylimines (HT-amination). In this transformation, 5-aryl aldehydes are subjected to N-toluenesulfonamide in the presence of BF3·OEt2 to effect imine formation and HT-cyclization, leading to 2-arylpiperidines and 3-aryl-1,2,3,4-tetrahydroisoquinolines in a one-pot procedure. We examined

  我们在此报告了一项通过N-甲苯磺酰亚胺的氢化物转移环化（HT-胺化）进行sp 3 C-H 键分子内胺化的研究。在此转化中，5-芳基醛在 BF 3 ·OEt 2存在下与N-甲苯磺酰胺反应，形成亚胺并进行 HT 环化，生成 2-芳基哌啶和 3-芳基-1,2,3,4-一锅法制备四氢异喹啉。我们检查了一系列醛底物的反应性作为其构象灵活性的函数。构象刚性较高的底物反应性更强，从而获得更高的所需产物产率。然而，连接N-甲苯磺酰亚胺和苄基 sp 3 C-H 键的烷基链上的单个取代基足以发生 HT 环化。此外，对各种芳烃的检查表明，氢 C-H 键的电子特性极大地影响了反应的效率。我们还发现这种转变是高度立体选择性的。2-取代醛产生顺式-2,5-二取代哌啶，而3-取代醛产生反式-2,4-二取代哌啶。立体选择性是热力学控制的结果。提出了哌啶环上芳烃和甲苯磺酰基之间的假烯丙基张力，以合理化芳基环位于轴向位置的异

  A direct result: Alkyl indium reagents are synthesized by the insertion of indium into alkyl halide mediated by CuCl. The synthetic utility of these reagents is demonstrated by their palladium‐catalyzed coupling with aryl halides (see scheme). The reagents are compatible with various functional groups, and this makes the protocol generally useful in organic synthesis. DMA=N,N‐dimethylacetamide, TB
