[Omim][BF4], a green and recyclable ionic liquid medium for the one-pot chemoselective synthesis of benzoxazinones

10.1016/j.tetlet.2010.01.122

The research presents an efficient one-pot chemoselective synthesis of 2H-benzo[b][1,4]oxazin-3(4H)-one derivatives from o-aminophenols using the ionic liquid [omim][BF4] and 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) at room temperature. The ionic liquid [omim][BF4] serves as a green and recyclable medium, allowing for the recovery and reuse of the IL over nine cycles without significant loss of performance. DBU acts as a crucial base in the reaction, facilitating the cyclization process to achieve high yields of the desired products in short reaction times. The procedure is mild, involves a broad range of starting materials, and demonstrates chemoselectivity, making it a significant advancement in the synthesis of benzoxazinones. The study also explores the use of various o-aminophenols and 2-bromoalkanoates, including less reactive substrates, showcasing the versatility and applicability of this method in organic synthesis.
