for the synthesis of substituted 4-alkylidene-tetrahydroquinoline derivatives, avoiding isomerization and oxidation. When non-substituted alkenes are used, the regioselectivity of the reaction can be directed towards the formation of an exocyclic or endocyclicdoublebond by choosing an adequate catalytic system. When the doublebond is substituted by an amide moiety, the exocyclic doublebond of E geometry
N-烯基取代的 2-卤代苯胺的 Mizoroki-Heck 反应是合成取代的 4-亚烷基-四氢喹啉衍生物的有效方案,可避免异构化和氧化。当使用未取代的烯烃时,通过选择合适的催化体系,反应的区域选择性可以指向形成环外或环内双键。当双键被酰胺部分取代时,可以选择性地获得 E 几何形状的环外双键。因此,该协议有效地合成了一系列 2-取代的四氢喹啉,在 C-4 位置具有外α,β-不饱和酰胺部分。

wide range of effect chemicals, are accessed by intramolecular amination of aromatic C–H bonds employing UV photolysis of N-chloroamines. The reactions show good functional group tolerance and allow access to a range of fused and bridged polycyclic structures. The homogeneous reaction conditions allow for the one-pot conversion of secondary amines to their arylated derivatives. Experimental and theoretical

An iron-mediated highly selective C–H sulfonylmethylation of anilinederivatives with p-toluenesulfonylmethyl isocyanide in a mixture solvent of H2O and PEG400 under an Ar atmosphere has been realized. This transformation proceeds with operational convenience, use of earth-abundant metal catalyst and nontoxic media, broad substrate scope, and good functional group tolerance. The current methodology
