Copper-Catalyzed Asymmetric Allylic Alkylation of β-Keto Esters with Allylic Alcohols

The asymmetric allylic alkylation reaction of β-keto esters catalyzed by copper complex tBuBOX-Cu(OTf)2 employing allylic alcohols as environmentally friendly electrophilic partner, is herein described. This new protocol renders in general the

Oxidative alkylation of 1,3-diarylpropenes using O2 catalysed by 2,3-dichloro-5,6-dicyano-benzoquinone and N-hydroxyphthalimide

A simple oxidative alkylation of 1,3-diarylpropenes with 1,3-dicarbonyl compounds is reported with O2 catalysed by a mixture of 2,3-dichloro-5,6-dicyano-benzoquinone, N-hydroxyphthalimide, CuBr and NiCl 2.

Synthesis of highly rigid phosphine-oxazoline ligands for palladium-catalyzed asymmetric allylic alkylation

A highly rigid spiro phosphine-oxazoline ligand skeleton with a spirocarbon stereogenic center was developed from 7-bromo-1-indanone. The catalytic performance of the ligand was demonstrated in palladium-catalyzed asymmetric allylic alkylation. Under opti

Pinacol Rearrangement and Direct Nucleophilic Substitution of Allylic Alcohols Promoted by Graphene Oxide and Graphene Oxide CO2H

Graphene oxide (GO) and carboxylic acid functionalized GO (GO–CO2H) have been found to efficiently promote the heterogeneous and environmentally friendly pinacol rearrangement of 1,2-diols and the direct nucleophilic substitution of allylic alcohols. In general, high yields and regioselectivities are obtained in both reactions using 20 wt % of catalyst loading and mild reaction conditions.

Ligand-Free, Quinoline N-Assisted Copper-Catalyzed Nitrene Transfer Reaction to Synthesize 8-Quinolylsulfimides

An efficient copper-catalyzed, quinolyl N-directed nitrene transfer reaction to 8-quinolylsulfides was described. A variety of 8-quinolylsulfimides with different functional groups were synthesized in moderate to high yields. The obtained 8-quinolylsulfimides were proved to be promising novel type of bidentate ligands in Pd(II)-catalyzed allylic alkylation.

The oxidative coupling of benzylic compounds catalyzed by 2,3-dichloro-5,6-dicyano-benzoquinone and sodium nitrite using molecular oxygen as a co-oxidant

Catalyzed by DDQ and NaNO2, the oxidative coupling between benzylic compounds and 1,3-dicarbonyls in the presence of molecular oxygen and HCOOH was developed. The 1% catalytic amount of DDQ is enough to complete the reaction. This system shows high efficiency and the coupling products are obtained in good to excellent yields within half an hour.

Rational design of sulfoxide-phosphine ligands for Pd-catalyzed enantioselective allylic alkylation reactions

A new type of chiral sulfoxide-phosphine ligands have been developed by a rational combination of two privileged scaffolds for Pd-catalyzed asymmetric allylic alkylation reactions. Under optimized conditions, generally high yields (up to 97%) and excellent enantioselectivities (up to >99% ee) were obtained.
