A straightforward synthetic method for the preparation of isocoumarins and 3-benzylidenephthalides via C–H olefination and oxidative coupling of readily available benzoicacids and vinylarenes was developed. The directing effect of the substituents on the benzoicacid allows for the synthesis of both types of lactone in pure form.
Reductive N-heterocyclization of 2-nitrostyrenes with carbonmonoxide in the presence of a catalytic amount of selenium proceeded efficiently to afford the corresponding indoles in moderate to good yields.
