Abstract:
The ability to generate chiral building blocks is of paramount importance to organic chemists. This problem presents itself most notably at the interface of chemistry and biology, where molecules of only a single enantiomer can induce function to many biological systems. In this context, recent developments in the field of organocatalysis, most notably the employment of chiral N-heterocyclic carbenes (NHCs) have shown much promise. Our group has recently shown that one possible chiral NHC catalyzed Stetter cyclization product of a conjugated triene, a highly functionalized cyclopentenone, cont
