The Ni(II)-catalyzed cross-coupling of arylboronic acids with allenoates is documented. The high regio- and stereoselectivity of the process enables a wide range of β-aryl β,γ-unsaturated esters to be prepared in good to excellent yields (up to 95%) and high E / Z -selectivity. Additionally, [3+2]-cascade sequence was observed when 2-formylphenylboronic acid was employed.

The introduction of lipophilic groups onto the ring nitrogen of nipecotic acid and guvacine, two known GABA uptake inhibitors, afforded potent, orally-active anticonvulsant drugs.A series of compounds is reported which explores the structure-activity relationships (SAR) in this series.Among the areas explored: side-chain SAR (aromatic-, heterocyclic-, and tricyclic-containing side chains) and modifications to the tetrahydropyridine ring.The benzhydrol ether-containing side chains afforded the most potent compounds with several exhibiting in vitro IC50 values for GABA uptake of 1 μM (including 5, Table I; 37, 43, Table IV; and 44, Table V).Compound 44 was selected for extensive evaluation and subsequently progressed to Phase 1 clinical trials with severe adverse effects seen after single dose administration to humans.

The reactions of arylazoxy aryl sulfones (1) with α,β-unsaturated esters and nitriles in the presence of a palladium(0) catalyst were found to give aryl-substituted esters and nitriles in good yield.
