Multisiteorganic–inorganichybridcatalysts have been prepared and applied in a new general, practical, and sustainable synthetic procedure toward industrially relevant GABA derivatives. The domino sequence is composed of seven chemical transformations which are performed in two one‐pot reactions. The method produces both enantiomeric forms of the product in high enantiopurity as well as the racemate
The present invention relates to a pharmaceutical composition comprising a plurality of layered double hydroxide nanoparticles and one or more pharmaceutically acceptable excipients, wherein the at least one aqueously unstable anionic drug compound is intercalated between the layers. The present invention also relates to a process for the preparation of such pharmaceutical compositions, the corresponding layered double hydroxides, as well as methods for their use in stablising unstable anionic drug compounds.
