Usage

Uses

(R)-Levetiracetam [REV] (Levetiracetam EP Impurity D), is the enantiomer to Levetiracetam [LEV] (L331500), the antiepileptic drug that is highly enantioselective. It is apparent that [LEV] is more potent than [REV] in terms of antiepileptic potency.

REGIOSELECTIVE OXIDATION OF HETEROCYCLIC ALPHA-AMINO AMIDES

The present invention relates to regioselective chemical and electrochemical processes for the preparation of an oxidized heterocyclic alpha-amino amide compounds. By applying specific catalysts or catalyst systems during chemical oxidation or by applying particular electrochemical oxidation conditions the present invention provides access to valuable alpha amino amide compounds, which are oxidized at the heterocyclic amino group by regioselective introduction of either a hydroxyl or a keto group. In a more particular embodiment, the present invention describes a chemical oxidation reaction, which advantageously is applicable in the enantioselective synthesis of valuable oxidized heterocyclic alpha-amino amide compounds, like levetiracetam, brivaracetam or the synthesis of piracetam. Another aspect of the present invention relates to a process for the electrochemical recycling of alkali perhalogenate oxidants as spent during said regioselective oxidation reactions of the invention. Still another aspect of the invention relates to the electrochemical preparation of perhalogenates.

Ionic Cocrystals of Etiracetam and Levetiracetam: The Importance of Chirality for Ionic Cocrystals

A striking variety of anhydrous and hydrated ionic cocrystals (ICCs) of the enantiopure antiepileptic drug (AED) levetiracetam and of its racemic intermediate etiracetam with the pharmaceutically acceptable salts CaCl2 and MgCl2 was synthesized and structurally characterized. The difference in the interaction of enantiopure and racemic compounds of interest with the inorganic salts was investigated. Variable-temperature X-ray powder diffraction (VT-XRPD) and calorimetric analyses (TGA and DSC) of all obtained ICCs showed a significant improvement in thermal stability with respect to pure racetams.

Ugi Four-Center Three-Component Reaction as a Direct Approach to Racetams

We report the synthesis of racetams, a diverse class of small molecule drugs, by means of the Ugi four-center three-component reaction (U4C-3CR). For the first time, γ-aminobutyric acid is employed as bifunctional input in the Ugi reaction. This protocol is simple, general, and allows one-pot access to a range of drugs and bioactive small molecules.
