Thesis (Ph.D.)--Northwestern University, 2016.

N-Heterocyclic carbene (NHC) catalysis has emerged as a powerful tool in organic synthesis to construct complex molecules based on polarity reversal (Umpolung). These unique Lewis bases have been used to catalytically generate homoenolates, enolates, and acyl anions. Recently, a new strategy has emerged that increases yields and stereoselectivity by leveraging additional activation modes: cooperative catalysis. This dissertation describes new advances in NHC cooperative catalysis. The first chapter surveys the entire field of cooperative carbene catalysis. The second chapter delves into the novel process of beta-protonation, which has its roots as an innocuous proof-of-concept reaction of homoenolate reactivity. This chapter concludes with the first high yielding, highly selective NHC/hydrogen bond donor-catalyzed beta-protonation. The third chapter deals with the studies toward the applications of this new cooperative catalysis platform towards solving old problems with new methodology. This dissertation is just a part of the larger continuum of NHC cooperative catalysis.
