“…6,8,9 Furthermore, quinoxalines can also serve as pesticides, 10 advanced materials in perovskite solar cells of high efficiency, 11 chemically/electrochemically switchable substances 12 and food flavouring agents. 13 In connection with their high biological and materialistic significance, several strategies have been developed for quinoxaline synthesis and most of them consist of a common condensation route of organic 1,2-diamines with other organic substances, including 1,2-diketones, 14 1,2-diols, 15 α-hydroxy ketones 8,9,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] and alkynes. 36 Among these strategies, the reaction of organic 1,2-diamines with α-hydroxy ketones or alkynes is relatively less explored, and requires metal-based catalysts/ oxidizing agents or non-renewable catalysts under harsh reaction conditions.…”
