  通过[3,3]-σ重排的（Diacetoxyiodo）芳烃的选择性邻位C-H氰基烷基化反应

  摘要：

  我们在本文中报告了在TMSOTf的辅助下，ArI（OAc）2与α-锡烷基腈之间的无催化剂交叉偶联。该转化将氰基烷基引入ArI（OAc）2的邻位，同时将芳基碘（III）还原为碘，从而提供α-（2-碘芳基）腈作为产物。此转换可在−78°C下5分钟内完成，并具有出色的功能组容限和有效的可扩展性。DFT计算表明，乙烯酮（芳基）碘鎓中间体的形成和随后的[3,3]-σ重排是关键步骤。

  Reactions of 4-substituted 1-[(difluoromethyl)sulfinyl]polyfluorobenzenes with phenolate anion

  摘要：

  The reactions of 4-substituted-polyfluorinated-[(difluoromethyl)sulfinyl]benzenes ([4-X-C6F4S(O)CHF2 [X = H, CF3 and C6F5S(O)]) with phenolate anion in benzene, Et2O and CH3CN have been investigated. The reactions of the substrate (X = H, CF3) and sodium phenolate in equal amounts resulted in the formation of mixtures of the starting compound, 2-phenoxyderivative and disubstituted products. The two-fold amount of the phenolate afforded the 2,6-disubstituted products for X = H in MeCN and for X = CF3 in Et2O. At the same time, 4-CF3-C6F4S(O)CHF2 in CH3CN gave a mixture of the 2,6- and 2,5-bis(phenoxy) derivatives. Quantum chemical calculations have been performed to explain this phenomenon. For X = C 6 F 5 S(0) in MeCN, the reaction was accompanied by sulfinyl moiety ipso-substitution.[GRAPHICS].

  A simple and efficient protocol was developed for the preparation of challenging α-aryl primary amides. This metal-free coupling process was triggered by TfOH-promoted electrophilic activation of α-silyl nitrile to generate keteniminium ion species, followed by reaction with aryl sulfoxide through [3,3]-sigmatrophic rearrangement to provide the target product. To the best of our knowledge, α-silyl

  开发了一种简单有效的方案来制备具有挑战性的 α-芳基伯酰胺。这种无金属偶联过程是由 TfOH 促进的 α-甲硅烷基腈的亲电活化以产生 keteniminium 离子物质引发的，然后通过 [3,3]-σ 重排与芳基亚砜反应以提供目标产物。据我们所知，α-甲硅烷基腈很少用作亲电子试剂。计算研究证实了高度亲电的酮亚胺中间体的短暂存在。

  A novel series of non-imidazole H-3-receptor antagonists was developed, by chemical modification of a potent lead H-3-antagonist composed by an imidazole ring connected through an alkyl spacer to a 2-aminobenzimidazole moiety (e.g., 2-[[3-[4(5)-imidazolyl]propyl]amino]benzimidazole), previously reported by our research group. We investigated whether the removal of the imidazole ring could allow retaining high affinity for the H-3-receptor, thanks to the interactions undertaken by the 2-aminobenzimidazole moiety at the binding site. The imidazole ring of the lead was replaced by a basic piperidine or by a lipophilic p-chlorophenoxy substituent, modulating the spacer length from three to eight methylene groups; moreover, the substituents were moved to the 5(6) position of the benzimidazole nucleus. Within both the 2-alkylaminobenzimidazole series and the 5(6)-alkoxy-2-amino-benzimidazole one, the greatest H-3-receptor affinity was obtained for the piperidine-substituted compounds, while the presence of the p-chlorophenoxy group resulted in a drop in affinity. The optimal chain length was different in the two series. Even if the new compounds did not reach the high receptor affinity shown by the imidazole-containing lead compound, it was possible to get good H-3-antagonist potencies with 2-aminobenzimidazoles having a tertiary amino group at appropriate distance.
