Abstract/Artist Statement
Abstract
Enantiomers are chiral molecules that are non-identical mirror images of each other—similar to the left and right hand. A pair of enantiomers exhibit indistinguishable physical properties, but contrasting biological properties. For example, the drug(S,S)-(+)-ethambutol can treat Tuberculosis, while (R,R)-(-)-ethambutol can inflict blindness. Therefore, a selective enantiomer production is vital to the preparation of modern efficient drugs.
This research is an introductory step aimed at developing chiral catalysts that selectively synthesize one enantiomeric product instead of the conventional 50/50 mixture of two enantiomers. We chose a cis-1,2-diaminocyclohexane (DACH) scaffold as the catalytic site for selective synthesis. Its two amino-groups were additionally equipped with supplementary attachments. By adding small quantities of the obtained DACH derivatives to appropriate chemical reactions, we established a fundamental starting point for further broader research towards chiral catalysts by demonstrating catalytic activity for the cis-DACH scaffold. The major accomplishments of this project are the design, optimization of synthesis, and preliminary testing of the model DACH-based catalyst.
Artist Statement
“What’s the point of studying organic chemistry?” is a familiar phrase heard in the pre-pharmacy community. People tend to think it’s a gruesome subject that “inflicts more headaches than smelling ammonia” (as some students might say). However, I developed a passion for organic chemistry and thus, pursued research. I was motivated by my intrinsic fascination with the subject, which was further enhanced when I realized its pharmaceutical significance. The potential to create a catalyst that can selectively synthesize one enantiomer highlights its importance in the preparation of modern efficient drugs. Thus, the results can prospectively improve the health and well-being of people worldwide—a potential worth appreciating and recognizing.
