  One-pot, solvent-free Pd(II)-catalyzed direct β-C-H arylation of carboxamides involving anhydrides as substrates via in situ installation of directing group

  摘要：

  A one-pot, multicomponent-type, solvent-free Pd(II)-catalyzed direct beta-C-H activation/arylation of carboxamides involving anhydrides as substrates via in situ installation of directing group (DG) is reported. Typically, the DG-assisted beta-C-H activation/arylation of carboxamides is a two-step process comprising the installation of DG and Pd(II)-catalyzed C-H arylation. We attempted a multicomponent-type reaction comprising an anhydride, a DG (e.g. 8-aminoquinoline), an aryl iodide in the presence of the Pd(II) catalyst and an appropriate additive. Different anhydrides, DGs, aryl iodides, catalysts and additives were screened to reveal the scope of this multicomponent-type C-H arylation reaction process and various beta-C-H arylated carboxamides were obtained in satisfactory to good yields.

  Auxiliary-Assisted Palladium-Catalyzed Arylation and Alkylation of sp² and sp³ Carbon−Hydrogen Bonds

  摘要：

  We have developed a method for auxiliary-directed, palladium-catalyzed beta-arylation and alkylation of sp(3) and sp(2) C-H bonds in carboxylic acid derivatives. The method employs a carboxylic acid 2-methylthioaniline- or 8-aminoquinoline amide substrate, aryl or alkyl iodide coupling partner, palladium acetate catalyst, and an inorganic base. By employing 2-methylthioaniline auxiliary, selective monoarylation of primary sp(3) C-H bonds can be achieved. If arylation of secondary sp(3) C-H bonds is desired, 8-aminoquinoline auxiliary may be used. For alkylation of sp(3) and sp(2) C-H bonds, 8-aminoquinoline auxiliary affords the best results. Some functional group tolerance is observed and amino- and hydroxy-acid derivatives can be functionalized. Preliminary mechanistic studies have been performed. A palladacycle intermediate has been isolated, characterized by X-ray crystallography, and its reactions have been studied.

  To demonstrate the efficiency of the process, various bidentate directing auxiliaries were used and 8-Aminoquinoline was found to be the best directing group for accomplishing the one-pot Pd(II)-catalyzed, sp3 CH activation and β-arylation of aliphatic/alicyclic carboxamides. A variety of aliphatic/alicyclic acid chlorides and aryl iodides were used as the substrates and several β-CH arylated carboxamide

  Palladium-catalyzed primary and secondary sp3 C–H bond arylation is reported. The method using diarylhyperiodonium salts as arylation reagents shows good functional group tolerance and proceeds under mild reaction conditions. The KIE experiments show that the C–H bond activation is the rate-determining step.

  PdCl2(CH3CN)(2)-catalyzed arylation of unactivated C(sp(3))-H bonds using (diacetoxyiodo)arenes as arylation reagents is reported. The reactivity of (diacetoxyiodo)arenes as arylation reagents is enabled in the presence of Cs2CO3 under the reaction conditions. This arylation method is highly efficient and occurs without the use of silver salt. The reaction tolerates a broad substrate scope that was not demonstrated by other silver salt-free C(sp(3))-H bond arylation conditions. The synthetic utility of the method is further illustrated in the synthesis of the psychotropic drug phenibut. A detailed mechanism study has been conducted to understand the reaction pathway.
