Publication Summary
Originally published in Angewandte Chemie, this publication reports a highly enantioselective method for synthesizing enantioisotopomers, molecules that are chiral solely because of deuterium substitution. The study addresses a longstanding challenge in chemistry by combining a scalable catalytic synthesis strategy with a novel analytical approach capable of determining both absolute configuration and enantiomeric excess for isotopically chiral molecules.
The researchers demonstrate the use of chiral tag rotational spectroscopy, which employs noncovalent chiral derivatization to enable quantitative chiral analysis without requiring reference samples. By eliminating the risk of racemization during derivatization and providing direct measurements of stereochemical outcomes, the approach offers a new framework for the synthesis and characterization of precisely deuterated molecules with potential applications in chemistry, drug development, and isotope labeling research.
