Meldrum's Acid (2,2-Dimethyl-1,3-Dioxane-4,6-Dione) (CAS: 2033-24-1), used as a pharmaceutical intermediate, intermediate of Meropenem series. Meropenem is another kind of parenteral administrated semi-synthetic carbapenem antibiotics after imipenem-cilastatin has entered into market in the United State. It can inhibit the bacterial cell wall synthesis through binding with the penicillin-binding proteins involved in cell wall synthesis (PBPs) through its covalent bond, thus playing its antibacterial effect.
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.
