Stereospecific cross-coupling of secondary alkyl β- trifluoroboratoamides

Sandrock, Deidre L.,Jean-Gerard, Ludivine,Chen, Cheng-Yi,Dreher, Spencer D.,Molander, Gary A.

, p. 17108 - 17110 (2011/03/01)

The stereospecific cross-coupling of enantioenriched nonbenzylic secondary alkyl boron compounds has been achieved. The high selectivity toward product formation over an undesired β-H elimination pathway is achieved via an intramolecular coordination of an ancillary carbonyl to the metal center in the diorganopalladium intermediate.
