General Description

Heptane-2,4-dione, also known as 2,4-heptanedione or diacetyl, is a chemical compound with the molecular formula C7H12O2. It is a yellowish-green liquid with a strong, pungent odor and is soluble in water. Heptane-2,4-dione is commonly used as a reagent in organic synthesis, especially in the production of various flavoring compounds. It is also a byproduct of fermentation processes and is found in many foods and beverages, contributing to their characteristic taste and aroma. However, prolonged exposure to heptane-2,4-dione can be harmful, as it has been associated with respiratory issues and potential carcinogenic effects. Therefore, it is important to handle and use this chemical with caution and in accordance with safety regulations.

METHOD FOR EXTRACTING ASYMMETRIC B-DIKETONE COMPOUND FROM B-DIKETONE COMPOUND

The present invention provides a method of extracting an asymmetric β-diketone compound from a β-diketone compound containing at least one symmetric β-diketone compound mixed in the asymmetric β-diketone compound, and the method includes the step (A) of adjusting a pH of a mixed solution of the β-diketone compound and water at 11.5 or more and dissolving the β-diketone compound into water to form a β-diketone compound solution and the step (B) of subsequently adjusting the pH of the β-diketone compound solution at 9.5 or less and recovering the asymmetric β-diketone compound of Chemical Formula 1 separated from the β-diketone compound solution. The present invention further includes at least either (a) a step of setting the upper limit of the pH of the mixed solution to 12.5 to form a β-diketone compound solution in the step (A) and bringing the β-diketone compound solution into contact with a hydrophobic solvent or (b) a step of setting the lower limit of the pH of the β-diketone compound solution to 8.0 in the step (B).

New insights into the reduction of β,δ-diketo-sulfoxides

New developments in the reduction of β,δ-diketo-sulfoxides, a reaction that affords important key intermediates for total synthesis, are described. We showed without ambiguity using NMR experiments, that the β-carbonyl group is totally enolised. This result is inconsistent with the previous hypothesis, which supposed the other tautomer (enolisation at the δ-position) as the major one. We propose a rationale to explain the side reactions occurring during the reduction of unprotected β,δ-diketo-sulfoxides and showed that judicious protection of the δ-carbonyl group gave all diastereoisomers of β-hydroxy-δ-ketosulfoxides.
