چکیده

An efficient method for the synthesis of 6-alkyl or 6-aryl purines (nucleosides) was developed via nickel-catalyzed Negishi cross-couplings of 6-chloropurines and organozinc halides. The ligand-free process gave good to excellent isolated yields at room temperature.

Nickel-catalyzed enantioselective cross-couplings of racemic secondary electrophiles that bear an oxygen leaving group.

To date, effective nickel-catalyzed enantioselective cross-couplings of alkyl electrophiles that bear oxygen leaving groups have been limited to reactions of allylic alcohol derivatives with Grignard reagents. In this Communication, we establish that, in the presence of a nickel/pybox catalyst, a variety of racemic propargylic carbonates are suitable partners for asymmetric couplings with organ...

Catalytic Enantioselective Cross-Couplings of Secondary Alkyl Electrophiles with Secondary Alkylmetal Nucleophiles: Negishi Reactions of Racemic Benzylic

We have developed a nickel-catalyzed method for the asymmetric cross-coupling of secondary electrophiles with secondary nucleophiles, specifically, stereoconvergent Negishi reactions of racemic benzylic bromides with achiral cycloalkylzinc reagents. In contrast to most previous studies of enantioselective Negishi cross-couplings, tridentate pybox ligands are ineffective in this process; however...

Metal-Catalyzed Cross-Couplings of Aryl Halides to Form C–C Bonds in Aqueous Media

Metal-catalyzed cross-coupling reactions have developed into a standard component of the synthetic chemist’s toolbox [1–4]. These reactions date to thework ofUllmann and Goldberg in the early 1900s on copper-promoted C–C and C–heteroatom bond formations. Copper remained the catalyst of choice for these reactions until the pioneeringwork ofHeck, Suzuki, Stille, Negishi, and others on palladium-c...
