A strategically novel synthetic method for the fluoroarylation of allenic ester was developed that enables the expedient construction of a host of β-fluoroalkyl-containing cinnamate derivatives. The reaction proceeds through visible-light-promoted gold redox catalysis, occurs smoothly under very mild reaction conditions, accommodates a large variety of functional groups, and more importantly allows the incorporation of fluorine and aryl groups with excellent regio- and stereoselectivity. The concomitant activation mode for both the allene motif and the hydrogen fluoride is key for the success of the reaction.

Nitrones and tert-butanesulfinyl imines undergo conjugate addition to alkyl allenoates under SmI2-mediated reductive coupling conditions to produce novel β-methylenyl-substituted γ -amino esters. The latter were readily transformed into the cor
