challenges associated with the lack of sufficiently active palladium catalysts. Currently used palladium catalysts are reactive only with electron-rich arenes, unless an excess of arene is used, which limits synthetic applications. Here we report a 2-pyridone ligand that binds to palladium and accelerates non-directed C–H functionalization with arene as the limiting reagent. This protocol is compatible with
hydroxymoylchlorides and 7-benzyloxy-3-chloro-4-methyl-coumarin hydroxymoylchlorides respectively with ethyl-3-aryl prop-2-enoate has been developed. The new compounds are screened for antibacterial activity. GRAPHICAL ABSTRACT
Discovery of Heterocyclic Nonacetamide Synaptic Vesicle Protein 2A (SV2A) Ligands with Single-Digit Nanomolar Potency: Opening Avenues towards the First SV2A Positron Emission Tomography (PET) Ligands
The role of the synapticvesicleprotein2A (SV2A) protein, target of the antiepileptic drug levetiracetam, is still mostly unknown. Considering its potential to provide in vivo functional insights into the role of SV2A in epileptic patients, the development of an SV2Apositronemissiontomography (PET) tracer has been undertaken. Using a 3D pharmacophore model based on close analogues of levetiracetam
The present invention relates to biaryl piperidine-based renin inhibitor compounds, and their use in treating cardiovascular events and renal insufficiency.

Lewis Base-Catalyzed Trifluoromethylsulfinylation of Allylic Alcohols: Stability-Oriented Divergent Synthesis
A novel strategy is demonstrated for Lewis base-activated trifluoromethylsulfinylation of allylic alcohols. Controllable synthesis of structurally varied allylic trifluoromethanesulfones via sigmatropic rearrangements was performed, and trifluoromethanesulfinate esters were achieved. This metal-free, catalytic divergent transformation features good functional group tolerance and late-stage modification
