项目摘要
PROJECT SUMMARY
The goal of this proposal is to generate innovative strategies for the asymmetric preparation of different
heterocyclic motifs, including N-containing compounds, that contain a chiral center. Realization of this goal is
expected to benefit medicinal chemistry campaigns because >59% of FDA approved drugs include a nitrogen-
containing ring system and >56% of FDA approved drugs contain a stereogenic center, the absolute
configuration of which is often critical to the activity of the molecule. To induce asymmetry in the proposed
processes, a Brønsted acid will be used to catalyze a stereoselective cyclization reaction, with a focus on the
use of commercially available chiral phosphoric acids. We hypothesize that the chiral phosphoric acid will
complex with the starting hydroxy and amino esters and nitriles to initiate a cyclization reaction that
preferentially generates one product enantiomer over the other. Our methods rapidly build complex molecules
under mild conditions, and our research will result in a significant advance over current state of the art.
Preliminary results support the validity of our approach and we will offer insight into the potential uses of the
generated products. The ring structures we will prepare are ideal candidates for further manipulation into other
biologically relevant structures or for diversification and evaluation themselves. Notably, these investigations
will be advanced primarily by M.S. and undergraduate student researchers.
