A new class of C2 symmetric bis-oxazaborolidinone is described. These compounds exhibit bidentate binding to carbonyl substrates. Using the Diels-Alder reaction the catalytic activity of these bis-Lewis acids is probed. Reaction rates and selectivities are observed that exceed the corresponding mono-Lewis acids. This novel system offers a potentially powerful new approach to asymmetric Lewis acid catalysis.
