The present invention relates to new compounds that show pharmacological activity towards the subunit α2δ of voltage-gated calcium channels (VGCC), especially the α2δ-1 subunit of voltage-gated calcium channels or dual activity towards the subunit α2δ of voltage-gated calcium channels (VGCC), especially the α2δ-1 subunit of voltage-gated calcium channels, and the µ-opiod receptor (MOR or mu-opioid). The invention is also related to the process for the preparation of said compounds as well as to compositions comprising them, and to their use as medicaments (formula (I)).
The visible-light photoredox/[Co(III)] cocatalyzed dehydrogenative functionalization of cyclic and acyclic styrylderivatives with carboxylic acids is documented. The methodology enables the chemo- and regioselective allylic functionalization of styrylcompounds, leading to allylic carboxylates (32 examples) under stoichiometric acceptorless conditions. Intermolecular as well as intramolecular variants

new catalyst system able to efficiently perform the synthesis of styrenes via CH bond functionalization and a subtle ligand modification are described. The high level of activity achieved allows for the synthesis of highly functionalized α,β‐substituted styrenes, even the elusive E‐configured trisubstitutedolefins, in a regio‐ and stereoselective manner. Mechanistic experiments allowed for the identification
functionalization of styryl carbon-carbon double bonds with triflamide is described viadual visible-light photoredox/cobaloxime catalysis. A range of allylictriflamides (20 examples) were isolated in moderate to good yields (up to 88%) under stoichiometric acceptorless conditions. Dedicated labelling, as well as spectroscopic experiments, enabled to shed light on the concatenated photo- and chemo-catalytic cycles
The reactions of CHCl2F with cyclopentadiene derivatives in the presence of aqueous KOH and triethylbenzylammonium chloride (TEBA) at −10 − +5∘ leads to the formation of fluoroaromatic compounds with a good yield:
