Abstract
Iridium photoredox catalysis enables a decarboxylative 1,4-addition of 2-oxo-2-(hetero)arylacetic acids to various Michael acceptors including α,β-unsaturated ester, ketone, amide, aldehyde, nitrile, and sulfone at room temperature. 2-Oxo-2-(hetero)arylacetic acids are easily accessible precursors of acyl anions through photoredox-catalyzed radical decarboxylation.
