Synthesis of Dichlorocyanomethyl-Functionalized Oxindoles by Cascade Reactions Initiated by Copper(I)-Catalytically Generated Dichlorocyanomethyl Radical

An efficient and convenient protocol for synthesis of dichlorocyanomethyl-functionalized oxindoles through the cascade reactions of dichlorocyanomethyl radical with N-arylacrylamides is reported. The electrophilic dichlorocyanomethyl radical, which is gen

Silver(I)-mediated oxidation/cyclization of acrylamides with alkyl trifluoroborates

A mild silver-mediated oxidative cyclization of acrylamides has been developed by using alkyl trifluoroborates as radical precursors. It proceeds through a tandem radical addition/cyclization process, in which two new carbon-carbon bonds were formed. This

Copper-Catalyzed Radical N-Demethylation of Amides Using N-Fluorobenzenesulfonimide as an Oxidant

An unprecedented N-demethylation of N-methyl amides has been developed by use of N-fluorobenzenesulfonimide as an oxidant with the aid of a copper catalyst. The conversion of amides to carbinolamines involves successive single-electron transfer, hydrogen-atom transfer, and hydrolysis, and is accompanied by formation of N-(phenylsulfonyl)benzenesulfonamide. Carbinolamines spontaneously decompose to N-demethylated amides and formaldehyde, because of their inherent instability.

Synthesis of oxindoles via Cu-mediated reactions between N-phenylacrylamides and ethyl 2-bromo-2-methylpropionate

A novel way of synthesizing alkylated oxindoles via Cu-mediated atom transfer radical addition reaction between N-phenylacrylamides and ethyl 2-bromo-2-methylpropionate has been described. It was found that the use of N,N,N′,N′-1,1,2,2,-tetramethylethylenediamine as ligand was important for achieving good yields. Additionally, the use of DMSO as solvent and running the reaction at 130 °C were also crucial. In some cases, the product can be further brominated when the reaction temperature was raised to 150 °C.

A tethering directing group strategy for ruthenium-catalyzed intramolecular alkene hydroarylation

We report a new catalyst design for N-heterocycle synthesis that utilizes an alkene-tethered amide moiety as a directing group for aromatic C-H activation. This tethering directing group strategy is demonstrated in a ruthenium-catalyzed intramolecular alk

Synthesis of oxindoles through silver-catalyzed trifluoromethylation-, difluoromethylation- and arylsulfonylation-cyclization reaction of N-arylacrylamides

Efficient synthesis of trifluoromethyl and difluoromethyl-substituted oxindoles was achieved by reacting Langlois reagent or Baran reagent with N-arylacrylamides. However, the reaction of aryl sulfinic acid sodium salts with N-arylacrylamides did not give the desulfinative products, instead, aryl sulfonated products were produced. Copyright

Direct annulations toward phosphorylated oxindoles: Silver-catalyzed carbon-phosphorus functionalization of alkenes

Silver screen: The AgNO3-catalyzed carbon phosphorylation of alkenes occurs by an alkene addition/cyclization cascade. Ag+ reacts with Ph2P(O)H to form the crucial active intermediate 1, which promotes the reaction. This method requires a cheap, nontoxic silver salt as the catalyst and substrates for the transformation are simple and readily accessible.
