An photosensitizer- and additive-free, visible-light-induced decarboxylative aminoalkylation/C−O coupling cyclization of enaminones with N-arylglycine for the synthesis of 3-aminoalkyl chromones has been achieved. This synthetic method features good functional-group tolerance, mild reaction conditions and no request of photocatalyst or additive, thus making this protocol more practical and sustainable.
