The synthesis of aryloxyl acrylates has been achieved through a new three-component synthetic method involving the assembly of phenols, acyl chlorides and Wittig reagents in the presence of a copper catalyst using glucose as a green ligand. β-Aryloxyl acrylates have been prepared with high diversity and in good to excellent yields involving the cascade formation of a new CC bond and a C(sp2)–O bond

A novel synthesis of beta-aryloxycarboxylic esters via asymmetric hydrogenation of the corresponding beta-aryloxy-alpha,beta-unsaturated esters has been demonstrated. Bis(norbornadiene)rhodium(I) tetrafluoroborate (1 mol %) and Walphos W008-1 were used to generate the saturated products with high enantioselectivity and in high yield. The tolerability of the reaction to a diverse range of substituents on the aromatic ring was also explored.
