Various geometrically pure (E)-alkenes have been synthesized by radical substitution of alcohol moieties generated via hydrogenabstraction within ethyl esters. These reactions occurred with high regioselectivity and gave a new access to 1-methyl-3-aryl-allyl esters.

A direct Pd(II)-catalyzed olefination of furans and thiophenes with allyl esters is demonstrated. Under the typical conditions, the dehydrogenative Heck coupling reactions of heteroarenes with allylic esters proceeded via a β-H elimination rather than a β-OAc elimination to give the corresponding γ-substituted allylic esters.

diastereo‐, and regioselectivity through catalytic asymmetric fluoroenolate alkylation with allylic acetates. The reaction proceeds undermildconditions and can be scaled up without compromising the asymmetric induction. The unique synthetic usefulness of the products is highlighted by the incorporation of additional functionalities and the formation of 3‐fluorinated oxindoles exhibiting an array of
