Asymmetric Synthesis Using Chiral Auxiliaries and Titanium Enolates

Michael Overbeek

Chiral auxiliary-mediated asymmetric aldol additions are an important method for asymmetric carbon-carbon bond formation. Dr. Daveid A. Evans from Harvard University has developed the use of a boron enolate to allow for specific stereochemistry, often called an ďEvanís Aldol Reactioní. The use of a titanium enolate, instead of a borony enolate, has been documented to create the opposite stereocenters when utilizing the Evanís Aldol methodology. This project describes an attempt to form an anti-Evans product with the addition of phenylacetaldehyde to R-(-)-4-Benzyl-3propionyl-2oxazolidinone. The use of an aldehyde substrate when utilizing a chiral titanium enolate has not been well documented in the literature.
