Alternatives to vinyl triflates for cross-coupling with arylboronic acids

Vinyl phosphates, mesylates, and tosylates derived from 1,3-dicarbonyl compounds are coupled with phenylboronic acid using nickel or palladium catalysts. An application to the area of 2-aryl carbapenem antibiotics is demonstrated. Alternative conditions for the nickel-catalyzed coupling of aryl mesylates are also reported.
