Modern approaches to the synthesis of 3-(acylamino)-and 3-(carbamoylamino)benzofuran-2(3H)-ones (microreview)

The microreview examines modern approaches to the synthesis of 3-(acylamino)- and 3-(carbamoylamino) benzofuran-2(3H)-ones described over the past 10 years (2011–2020). The methods are subdivided into groups depending on the used starting reagents and the reactions underlying them. Approaches based on the use of phenols as starting compounds, methods of modification of benzofuranone derivatives, as well as some other methods are considered.
