- 요약Atropisomerism (or axial chirality) arises from restricted bond rotation most typically in a Csp2-Csp2 σ bonds, wherein the neighboring substitutions across the atropisomeric bond contribute energy differences through steric strain. Also referred to as axial chirality, stable atropisomerism (i.e., creating significant steric strain across the bond to give rise to two isolable enantiomers) can be very challenging to achieve. However, in stabilizing the atropisomeric axis this leads to two unique compounds that have been shown to possess profound activities in many areas of research. Within the last decade, the Gustafson group at San Diego State University has since focused on leveraging atropisomerism on its importance to drug discovery with emphasis of exploring Nheterocyclic pharmaceutically relevant scaffolds. Along with challenges to achieving stable atropisomerism within a compound, it is very often equally difficult to then furnish enantiopure atropisomers. Traditional resolution methods such as chiral separation can be inconducive in time and resources and sometimes impractical for scaffold exploration.To address this bottleneck, the Gustafson group began a marital chemistry program in developing new chemical reactions that expedite access to these atropisomeric compounds (Chapter 1). Currently, we have several atroposelective synthetic strategies via nucleophilic aromatic substitutions (SNAr, Chapter 2) which have successfully furnished atropisomeric 3- arylpyrrolopyrimidines and 3-arylquinolines. Post-functionalization from the atroposelective SNAr methods have also potentially are useful to synthesize chemical probes (Chapter 3). Furthermore, nucleophilic substitutions outside of SNAr have also been widely used for the synthesis of pharmaceutically relevant compounds (Chapter 4, vicarious nucleophilic substitution (VNS) and atroposelective alkylation by acid-catalyzed directed 'nucleophilic radicals' (Minisci chemistry)). We believe our research will impact the current need for atroposelective nucleophilic substitution strategies towards pharmaceutically relevant scaffolds in the field of asymmetric catalysis. Lastly, we shared that these chemistries furnished enantioenriched pharmaceutically relevant scaffolds in desired yields that would be useful to ongoing medicinal chemistry efforts.
