cross-coupling of homoallylic tosylate substrates using boronic acids and pinacol esters is reported. The reaction uses 2-(4,5-dihydro-2-oxazolyl)quinoline (quinox) as a ligand and is performed at ambient temperature. The scope of the reaction is broad in terms of both the boronate transmetalating reagent and the substrate and includes secondary tosylates. Mechanistic studies support an alkene-mediated

The disclosure provides monoamine neurotransmitter releaser and/or monoamine uptake inhibitor compounds having biogenic amine transporter activity but lacking substantial activity at 5-HT2 receptor subtypes. The phenethylamine or vinylogous phenethylamine compounds of the disclosure are useful in treating diseases, conditions and/or disorders mediated by activity of one or more of the monoamine neurotransmitters.

relay Suzuki cross-coupling reactions of secondaryalkyltosylates, featuring a sterically-hindered oxidative addition and precise control of β-hydride elimination, are reported. The identification of a linear free energy relationship between the relative rates of substrate consumption and the electronic nature of the substrate alkene suggests that the oxidative addition requires direct alkene involvement
