  • General Characteristics

The direct coupling between unsubstituted aromatic rings and olefins in the presence of palladium catalysts is called the Fujiwara-Moritani reaction. This reaction is one of the early examples of transition metal-promoted C-H activation reactions.

In terms of chemical transformation, this reaction corresponds formally to the oxidative Mizoroki-Heck reaction.

  • Examples

Modifications and applications of the Fujiwara-Moritani reaction have been studied actively in recent years, especially using substrates containing directing groups. A number of highly regioselective systems have been reported, which was difficult under the original conditions.

Jin-Quan Yu developed an efficient carboxylic acid-directed catalytic system[1] and used it elegantly in the convergent total synthesis of (+)-lithospermic acid.[2]
