  醛和2-乙烯基苯胺的多取代喹啉的碳催化级联合成

  摘要：

  氧化活性炭 (oAC) 催化邻乙烯基苯胺和醛形成多取代喹啉。该反应通过缩合、电环化和脱氢以级联方式进行，并提供了范围广泛的具有烷基和/或芳基取代基的喹啉，如 40 个例子所示。无金属催化过程允许合成各种多取代喹啉的异质协议。机理研究表明，oAC 中的酸基和醌基都是催化歧管的组成部分。

• Divergent Syntheses of Indoles and Quinolines Involving N1–C2–C3 Bond Formation through Two Distinct Pd Catalyses
  作者：Su San Jang、Young Ho Kim、So Won Youn

  annulative couplings of 2-alkenylanilines with aldehydes using alcohols as both the solvent and hydrogen source have been developed. These domino processes allow divergent syntheses of two significant N-heterocycles, indoles and quinolines, from the same substrate by tuning reaction parameters, which seems to invoke two distinct mechanisms. The nature of the ligand and alcoholic solvent had a profound

  已经开发了使用醇作为溶剂和氢源的Pd催化的2-链烯基苯胺与醛的环状偶联。这些多米诺过程允许通过调节反应参数从同一底物上不同的合成两个重要的N杂环（吲哚和喹啉），这似乎调用了两种不同的机制。配体和醇溶剂的性质对这些方案的选择性和效率产生了深远的影响。尤其值得注意的是，吲哚的形成是通过克服两个重大挑战而实现的：烯烃的区域选择性加氢palpalpalation和随后的Csp 3 -Pd物种与反应性较低的亚胺之间的后续反应。
• A nickel-catalyzed <i>anti</i>-carbometallative cyclization of alkyne–azides with organoboronic acids: synthesis of 2,3-diarylquinolines

  An anti-carbonickelative cyclization via reversible alkenylnickel E/Z isomerization of 2-azido phenyl propargyl alcohols with aryl boronic acids is achieved using Ni(acac)2 as the catalyst to access 2,3-diaryl quinolines. It represents a rare example of trapping the vinyl metal intermediate with a nitrogen center, a non-carbon center electrophile.

• Unexpected Annulation between 2-Aminobenzyl Alcohols and Benzaldehydes in the Presence of DMSO: Regioselective Synthesis of Substituted Quinolines

  alcohols, benzaldehydes, and DMSO to quinolines has been disclosed. For the reported annulation between 2-aminobenzyl alcohols and benzaldehydes, the change of the solvent from toluene to DMSO led to the change of the product from the diheteroatomic cyclic benzoxazines to monoheteroatomic cyclic quinolines. This annulation can be used to synthesize regioselectively different substituted quinolines

  2-氨基苯甲醇、苯甲醛和 DMSO 与喹啉发生了意想不到的环化反应。对于已报道的 2-氨基苯甲醇和苯甲醛之间的环化反应，溶剂从甲苯变为 DMSO 导致产物从二杂原子环状苯并恶嗪变为单杂原子环状喹啉。通过选择不同的 2-氨基醇、醛和亚砜作为底物，这种环化可用于合成区域选择性不同的取代喹啉。有趣的是，将取代基引入亚砜的 α 位会导致产物喹啉中苯甲醛和亚砜之间的位置互换。在对照实验和文献的基础上，提出了一种合理的环化机制。
• Carbolithiation of <i>o</i>-Amino-(<i>E</i>)-Stilbenes:  Diastereoselective Electrophile Substitution with Applications to Quinoline Synthesis

  [GRAPHICS]A regioselective carbolithiation of o-amino-(E)-stilbenes has been achieved with a series of alkyllithiums when THF is employed as the reaction solvent. The use of other solvents, such as diethyl ether or hydrocarbons, leads to a pronounced loss in regioselectivity. Moreover, high levels of diastereoselectivity have been obtained following reaction of the lithiated intermediate in THF with different electrophiles such as MeOD, CO2, and Bu3SnCl. It was shown that diastereoselectivity was influenced by the ortho-amino substituent and the alkyllithium utilized for carbolithiation with N-Boc substituent and t-BuLi proving optimal. In the case of carbolithiated intermediate 3a, obtained from the reaction of N-Boc substituted stilbene with t-BuLi, H-1 and C-13 NMR analysis revealed predominantly one diastereoisomer which was stable at room temperature. Application of the carbolithiation/electrophile reaction methodology to the synthesis of six-membered quinoline ring systems is demonstrated with substituted 3,4-dihydroquinolin-2-ones, 1,2,3,4-tetrahydroquinolines, 1,4-dihydroquinolines, and quinolines all prepared by a common cascade route.
