Enantioselective Decarboxylative Alkylation Reactions: Catalyst
α-Quaternary ketones are accessed through novel enantioselective alkylations of allyl and propargyl electrophiles by unstabilized prochiral enolate nucleophiles in the presence of palladium complexes with various phosphinooxazoline (PHOX) ligands. Excellent yields and high enantiomeric excesses are obtained from three classes of enolate precursors: enol carbonates, enol silanes, and racemic β-k...
متن کاملCovalent functionalization of N-doped graphene by N-alkylation.
Nitrogen doped graphene was modified by N-alkylation using a combination of phase transfer catalysis and microwave irradiation. The resulting derivatives of N-doped graphene were analysed showing that the bandgap of the material varied depending on the alkylation agent used.
متن کاملCopper-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...
متن کاملEfficient and selective N-alkylation of amines with alcohols catalysed by manganese pincer complexes
Borrowing hydrogen (or hydrogen autotransfer) reactions represent straightforward and sustainable C-N bond-forming processes. In general, precious metal-based catalysts are employed for this effective transformation. In recent years, the use of earth abundant and cheap non-noble metal catalysts for this process attracted considerable attention in the scientific community. Here we show that the ...
متن کاملReactions of Oxime Dianions: Stereospecificity in Alkylation
n carbon.L However, no information on the stereochemistry of the alkylated products was ever reported. We now wish to report total stereospecificity in the formation and alkylation of the a-carbon, oxygen-dianions of aliphatic ketoximes. Treatment of acetoxime 1 with two equivalents of n-BuLi in THF at O°C for 15 minutes resulted in the formation of exclusively the x dianion 2, which upon deute...
