| 2,2-Dimethyl-1,3-dioxane-4,6-dione Usage And Synthesis |
| Description | Meldrum's acid, also known as 2,2-dimethyl-1,3-dioxane-4,6-dione, is an organic compound with the formula C6H8O4. The compound was first made in 1908 by Andrew Norman Meldrum by a condensation reaction of malonic acid with acetone in acetic anhydride and sulfuric acid. Meldrum misidentified the structure as a β-lactone of β-hydroxyisopropylmalonic acid. Yet Meldrum's acid has a high acidity with a pKa of 4.97, because like ascorbic acid, deprotonation at the methylene next to the carbonyls produces a stable enolate. Because of this property Meldrum's acid like malonic acid is a reactant in Knoevenagel condensations. |
| Chemical Properties | The compound appears as white to beige crystals. It has a melting point of 94-95℃ (decomposition), is insoluble in water, and is soluble in ethanol and acetone. |
| Uses | Meldrum's acid serves as an intermediate in a variety of organic synthesis reactions. It is commonly used as an alternative to acyclic malonic esters and generally acts as a C3O2 synthon in organic synthesis. |
| Uses | An antimicrobial agent |
| Application | 2,2-Dimethyl-1,3-dioxane-4,6-dione was used in the synthesis of: macrocyclic β-keto lactone 4-pyridyl-substituted heterocycles 2-substituted indoles isofraxidin. |
