I found the field of Chemistry very interesting. Saw the article Disparate Catalytic Scaffolds for Atroposelective Cyclodehydration published in 2019. Quality Control of 4-Nitrobenzoic acid, Reprint Addresses Miller, SJ (corresponding author), Yale Univ, Dept Chem, New Haven, CT 06520 USA.; Toste, FD (corresponding author), Univ Calif Berkeley, Dept Chem, Berkeley, CA 94720 USA.; Sigman, MS (corresponding author), Univ Utah, Dept Chem, 315 South 1400 East, Salt Lake City, UT 84112 USA.. The CAS is 62-23-7. Through research, I have a further understanding and discovery of 4-Nitrobenzoic acid
Catalysts that control stereochemistry are prized tools in chemical synthesis. When an effective catalyst is found, it is often explored for other types of reactions, frequently under the auspices of different mechanisms. As successes mount, a unique catalyst scaffold may become viewed as privileged. However, the mechanistic hallmarks of privileged catalysts are not easily enumerated or readily generalized to genuinely different classes of reactions or substrates. We explored the concept of scaffold uniqueness with two catalyst types for an unusual atropisomerselective cyclodehydration: (a) C-2-symmetric chiral phosphoric acids and (b) phosphothreonine-embedded, peptidic phosphoric acids. Pragmatically, both catalyst scaffolds proved fertile for enantioselective/atroposelective cyclodehydrations. Mechanistic studies revealed that the determinants of often equivalent and high atroposelectivity are different for the two catalyst classes. A data-descriptive classification of these asymmetric catalysts reveals an increasingly broad set of catalyst chemotypes, operating with different mechanistic features, that creates new opportunities for broad and complementary application of catalyst scaffolds in diverse substrate space.
