The first cobalt-catalyzed asymmetric Kumada cross-coupling with high enantioselectivity has been developed. The reaction affords a unique strategy for the enantioselective arylation of α-bromo esters catalyzed by a cobalt-bisoxazoline complex. A variety of chiral α-arylalkanoic esters were prepared in excellent enantioselectivity and yield (up to 97% ee and 96% yield). The arylated products were transformed

The present invention relates to compounds of formula (I) wherein Q is selected from O or S; R1 is a non-aromatic heterocyclic group comprising at least one ring nitrogen atom, wherein R1 is attached to the sulfur atom of the sulfonylurea group by a ring carbon atom, and wherein R1 may optionally be substituted; and R2 is a cyclic group substituted at the α-position, wherein R2 may optionally be further substituted. The present invention further relates to salts, solvates and prodrugs of such compounds, to pharmaceutical compositions comprising such compounds, and to the use of such compounds in the treatment and prevention of medical disorders and diseases, most especially by the inhibition of NLRP3.

The present invention relates to compounds of general formula (I) having dual pharmacological activity towards both the sigma (σ) receptor, and the μ-opiod receptor and more particularly to diazaspiro undecane compounds having this pharmacological activity, 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.
4-Aryl-1-oxa-4,9-diazaspiro[5.5]undecane Derivatives as Dual μ-Opioid Receptor Agonists and σ<sub>1</sub>Receptor Antagonists for the Treatment of Pain
The synthesis and pharmacological activity of a new series of 1-oxa-4,9-diazaspiro[5.5]undecane derivatives as potent dual ligands for the sigma-1 receptor (σ1R) and the μ-opioid receptor (MOR) are reported. The different positions of the central scaffold, designed using a merging strategy of both target pharmacophores, were explored using a versatile synthetic approach. Phenethyl derivatives in position
