A highly efficient and clean method has been developed for the synthesis of 3-oxoindeno[2,1-c]isocoumarins and 3-oxoindeno[2,1-c]isoquinolinones from 4-phenyl-3-isocoumarincarboxylic acids and 4-phenyl-3-isoquinolinonecarboxylic acids, respectively.

Reaction of Ph3P=CH-COOEt with ortho benzoyl benzoic acid derivates offers an easy and surprising entry to functional isocoumarins via the thermal decomposition of the keto-ylide intermediates or by subsequent oxidation of the expected indenones.
