Adviser: F. Dean Toste.

Thesis (Ph.D.)--University of California, Berkeley, 2008.

Described herein is the first enantioselective Conia-ene reaction, catalyzed by a chiral Pd(II) complex. The reaction forms products containing all-carbon quaternary stereocenters in good yield and high enantiomeric excess.

520 $a Described herein is the first enantioselective Conia-ene reaction, catalyzed by a chiral Pd(II) complex. The reaction forms products containing all-carbon quaternary stereocenters in good yield and high enantiomeric excess.
520 $a Using similar methodology, the enantioselective cyclization of silyloxy 1,6-enynes is also presented. A broad array of substrates cyclize efficiently to give products containing chiral all-carbon quaternary stereocenters in high enantiomeric excess.
520 $a A remaining challenge in the field of organic synthesis is the development of synthetic methods that form only one enantiomer of desired products. One of the most efficient and successful methods toward this end is the use of chiral catalysts to affect enantioselective organic transformations.
520 $a The application of these methods in the context of target oriented synthesis is described. Using the enantioselective cyclization of silyloxy 1,6-enynes, the first total synthesis of (-)-laurebiphenyl is accomplished. Using the analogous cyclization of enamidynes, a synthesis of the kopsifoline core is also disclosed.
520 $a Appendix A discusses attempts at rhenium catalyzed alkyne metathesis. A new rhenium-alkylidyne complex is disclosed. Appendix B presents initial results of an investigation into nickel mediated cross coupling of aryl nitriles with trimethylsilyl trifluoromethane.
