Abstract

Condensation of 4-aroyl-5-aryl-2,3-furandiones (1a,b) and ethyl 4,5-dioxo-2-phenyl-4,5-dihydrofuran-3-carboxylate (1c) with various 1,2phenylenediamines (2d-f) gave 2(1H)-quinoxalinone derivatives, 1,3-diaryl-2-(3-oxo-3,4-dihydro-2-quinoxalinyl)-1,3-propanediones (3ae,af,bd,be,bf) and ethyl 3-aryl-3oxo-2-(2-oxo-1,2-dihydro-2-quinoxalinyl)propanoate (3cd,ce). Alkaline treatment of 1,3-propanediones (3af,bd,bf) gave corresponding 3-aroylmethy1-2(1H)quinoxalinones (4af,bd,bf).
