Copper-catalyzed N-alkylation of indoles by N-tosylhydrazones

An efficient method for the direct N-alkylation of indoles via copper-catalyzed reductive cross coupling between N-tosylhydrazones and indole reagents has been developed. The reaction was performed in the presence of copper iodide and potassium hydroxide by utilization of tri(p-tolyl)phosphine as a ligand. A wide variety of N-alkylated indoles were obtained in moderate to good yields. The appli...

Palladium-catalyzed benzylation of heterocyclic aromatic compounds.

Broadly applicable palladium-catalyzed heteroarene benzylation reactions are described with a focus on the most challenging heterocyclic classes under traditional benzylation techniques such as sulfur-containing heterocycles and those bearing functional groups that would be incompatible with reactions requiring Lewis acids and/or strong bases.

Copper-catalyzed reductive coupling of tosylhydrazones with amines: a convenient route to α-branched amines.

A general procedure for the reductive coupling of N-tosylhydrazones with amines in the presence of Cu(acac)(2) and Cs(2)CO(3) has been developed. The protocol is very effective and chemoselective with various primary and secondary aliphatic amines, aminoalcohols as well as azole derivatives to give α-branched amines in good yields.

Copper-catalyzed direct alkylation of heteroarenes.

An efficient and broadly applicable process is reported for the direct alkylation of C-H bonds in heteroarenes, privileged scaffolds in many areas of science. This reaction is based on the copper-catalyzed addition of alkyl radicals generated from activated secondary and tertiary alkyl bromides to a wide range of arenes, including furans, thiophenes, pyrroles, and their benzo-fused derivatives,...
