An unprecedented decarboxylativealkylation reaction of β‐keto acids with isochromans has been developed underoxidativeconditions. A range of β‐keto acids smoothly undergo decarboxylativealkylation with isochromans in the presence of 2,2,6,6‐tetramethylpiperdine‐1‐oxoammonium hexafluorophosphate to give structurally diverse 1‐acylmethylisochromans in moderate to excellent yields with extremely high
