C–C Coupling Repertoire Grows ... Organic Synthesis: Reaction eases addition of chiral carbon centers to aryl groups

 

09224-notw8-suzuki
REVIVAL
This new reaction combines chiral secondary and tertiary boronic esters (left) with lithiated aryls to form intermediates that rearrange upon electrophile addition, yielding aryl-alkyl coupling products.
The revival of a nearly 50-year-old technique for forming carbon-carbon bonds may help ease the synthesis of aryl derivatives, such as drug candidates.
Varinder K. Aggarwal and coworkers at the University of Bristol, in England, have taken a venerable but neglected synthesis called Zweifel olefination and made it new again (Nat. Chem. 2014, DOI: 10.1038/nchem.1971).
