CO_2 Incorporation Reaction Using Arynes:Straightforward Access to Benzoxazinone

摘要

In view of the strong demand for efficacious utilization of CO_2 as a C_1 source,development of CO_2 incorporation reactions into valuable organic molecules has been an essential subject in synthetic organic chemistry.Recently,we have demonstrated that diverse benzo-annulated heterocyclic structures can directly be fabricated via three-component coupling reactions using arynes,in which zwitterions arising from nucleophilic attack of neutral nucleophiles to arynes act as pivotal intermediates.
