Synthesis of dissymmetric BINOL derivatives using solid phase organic chemistry

Andrew N. Lowell, J. Brian Hewgley, Rajesh Kamble, and Marisa C. Kozlowski. University of Pennsylvania, Philadelphia, PA

Substituted BINOL derivatives fulfill useful roles as chiral ligands. While chemists have the ability to make symmetric BINOL variants easily using solution phase chemistry, dissymmetric variants have proven elusive. The difficulty arises in isolating appreciable amounts of product from the statistical mixture of symmetric and dissymmetric products. By using our 1,5-diaza-cis-decalin copper catalysts and solid phase organic chemistry, libraries of dissymmetric BINOL derivatives are easily accessible.
