Research Interests

The last decade has seen a rapid expansion in the interest in the asymmetric synthesis of 1-substituted phosphonates. The unique properties of phosphorus provide a fascinating and challenging approach to stereoselective reactions. Our goal is to examine the use of chiral phosphonamides and phosphonates in stereoselective reactions. We reported the first example of a lathanide chiral catalyst in the addition of simple phosphites to achiral aldehydes. More recently, we discovered some promising titanium alkoxide systems. We are attempting to expand the chemistry of allylic hydroxy phosphonamides and phosphonates formed in the chemistry discussed above. Allylic hydroxy phosphonates are similar to regular allylic alcohols and should undergo similar chemistry. However, the presence of the phosphonate significantly alters the electronics of the system, and enables control of both regiochemistry and stereochemistry. Our initial work focused on the palladium catalyzed addition of amines to the carbonate derivatives of allylic hydroxy phosphonates, and several examples of this reaction have been performed. The rearrangement proceeds with complete retention of chirality. A number of 3,3 sigmatropic rearrangements and alkene addition reactions have been studied. The newly developed chemistry of the hydroxy phosphonates is being applied toward the synthesis of the cathepsin B, cruzain, and renin inhibitors, lactones and lactams.

Psammapsylin, fistularin, and the bastadins are related metabolites isolated from sponges found worldwide. This family of highly brominated compounds possess wide ranging biological activity, including anti-HIV activity, and anti-tumor properties. They are related in their biosynthetic origin, as oxidation products of tyrosine. We are exploring biomimetic approaches to the synthesis of several of these metabolites. The development of new methodology is guided by the biosynthetic pathway proposed for the formation of the tyrosine metabolites. As an extension of this project, we recently initiated research into methods for the facile synthesis of unsymmetric biaryl ethers.
