The invention concerns the field of synthesis organic chemistry applied to the pharmaceutical field and concerns novel derivatives of 4-hydroxybutanoic acid and its higher homologue, 5-hydroxypentanoic acid, their crotonic homologues, pharmaceutical compositions containing them and their pharmaceutical uses. Said novel derivatives are capable of binding with γ-hydroxybutyrate (GHB)-specific receptors and hence capable of exhibiting agonist or antagonist properties, in particular for treating sleep disorders, anxiety and general diseases of the central nervous system. The invention also concerns compounds of general formula (I) wherein the substituents are as defined in the description.
Oxyfunctionalization of abundant carboxylic acids represents a direct approach to synthesizing α-hydroxyacids, which are valuable intermediates of various active pharmaceutical ingredients. Although ideal, the transformation is yet to be accomplished. Herein, enantiocomplementary C(sp3)–H oxyfunctionalization for the synthesis of α-hydroxyacids was realized by a cooperative strategy of substrate
