Summary
Originally published in Nature, this paper describes a method for preparing precisely deuterated cyclohexene isotopologues and stereoisotopomers from benzene. Deuterium plays an important role in pharmaceutical research, mechanistic studies, and drug development, but selectively placing deuterium atoms at specific locations within a molecule can be challenging. The authors developed a four-step synthetic approach that uses a tungsten complex to enable controlled incorporation of deuterium into cyclohexene.
Using combinations of deuterated and non-deuterated reagents, the researchers achieved precise control over both the position and stereochemistry of deuterium incorporation. The method produced 52 unique stereoisotopomers across 10 different cyclohexene isotopologues, demonstrating a systematic approach for preparing isotopically labeled building blocks. The work highlights the potential of stereoselectively deuterated compounds to support pharmaceutical research, improve drug properties, and provide insights into drug metabolism and distribution
