A straightforward synthetic method for the preparation of isocoumarins and 3-benzylidenephthalides via C-H olefination and oxidative coupling of readily available benzoic acids and vinylarenes was developed. The directing effect of the substituents on the benzoic acid allows for the synthesis of both types of lactone in pure form.

Several N,N-diethyl-2-acylmethylbenzamides (6) were prepared from N,N- diethyl-2-toluamides (4), and the ketoamides (6) were easily cyclized to the corresponding 3-substituted isocoumarins (8) by heating in acetic acid or xylene. This simple procedure was
