The lipase-catalyzed acetylation of a broad spectrum of racemic 2-hydroxy acids 1 to their 2-acetoxy acids 2 was shown to proceed with high enantioselectivity. Thus, the microbial lipases, in particular from Candidaantarctica and Burkholderiaspecies, are convenient biocatalysts for the synthesis of optically active 2-hydroxy acids in excellent enantioselectivity (ee values up to > 99%). The absolute

The present invention relates to piperazinyl and piperidinyl quinazolin-4(3H)-one derivatives having pharmacological activity towards the (formula (I)) subunit, in particular the (formula (2)) subunit, of the voltage-gated calcium channel, in particular having dual pharmacological activity towards both the (formula (I)) subunit, in particular the (formula (2)) subunit, of the voltage-gated calcium channel and the µ-opioid receptor. The present invention also relates to processes of preparation of such compounds, to pharmaceutical compositions comprising them, and to their use in therapy, in particular for the treatment of pain.
