Controlled synthesis of CD₂H-ketones.

Area of Science:

• Organic Chemistry
• Isotope Chemistry

Background:

• Partially deuterated compounds, such as those with CD2H groups, are valuable in various scientific fields.
• General synthetic methods for these specific compounds are currently lacking.

Purpose of the Study:

• To establish a convenient and general synthetic route for CD2H-methyl ketones.
• To enable the production of compounds with fine-tuned metabolic control for drug discovery.
• To facilitate the development of novel multifunctional probes for spectroscopic analysis.

Main Methods:

• Coupling of esters with bis[(pinacolato)boryl]methane.
• Trapping the intermediate with deuterium oxide (D2O).

Main Results:
