K2CO3/H2O in [omim][BF4] ionic liquid: A green medium for efficient room-temperature synthesis of N-substituted 1,4-benzoxazin-3-ones

A medium consisting of K2CO3 and H2O in [omim][BF4] ionic liquid (IL) was used to synthesize N-substituted 2H-benzo[b][1,4]oxazin-3(4H)-one derivatives from their corresponding o-aminophenols and 2-bromoalkanoates. As a result, chemoselective formation of benzoxazinones in high yields has been observed at room temperature. After the reactions and separation of the products, the IL was recovered and successfully reused in subsequent reactions without significant loss of activity.
