Retropinacol/cross-pinacol coupling reactions - A catalytic access to 1,2-unsymmetrical diols

Scheffler, Ulf,Stoesser, Reinhard,Mahrwald, Rainer

supporting information, p. 2648 - 2652,5 (2012/12/12)

A new concept to access unsymmetrical 1,2-diols with high yields is reported. This new methodology is based on a retropinacol/cross-pinacol coupling process. This transformation is characterized by its operational simplicity and very mild reaction condi tions.
