A stereocontrolled synthesis of α-amino-α'-alkoxy ketones is described. This pH-neutral copper(I) thiophene-2-carboxylate (CuTC)-catalyzed cross-coupling of amino acid thiol esters and chiral nonracemic α-alkoxyalkylstannanes gives α-amino-α'-alkoxy ketones in good to excellent yields with complete retention of configuration at the α-amino- and

Fragment-based screens test multiple low-molecular weight molecules for binding to a target. Fragments often bind with low affinities but typically have better ligand efficiencies (DeltaG(bind)/heavy atom count) than traditional screening hits. This efficiency, combined with accompanying atomic-resolution structures, has made

[figure: see text] A new methodology for the synthesis of substituted alkynes is described. In the presence of copper(I) thiophene-2-carboxylate (CuTC) or copper (I) 3-methylsalicylate (CuMeSal), the palladium-catalyzed cross-coupling of thioalkyne derivatives with boronic acids affords functionalized alkynes in yields
