摘要

Abstract: A one-step synthesis of ethyl 1, 2-dihydronaphtho [2, 1-b] furan-2-carboxylates 2a– g from substituted 2-naphthols and ethyl 2, 3-dibromopropanoate is described. 3, 4- Dibromobutan-2-one and 2-chloroacrylonitrile react with 2-naphthol (1a) to afford the corresponding 2-cyano-or 2-acetylnaphtho [2, 1-b] furans 6 and 7, respectively. Key words: 2- naphthols, ethyl 1, 2-dihydronaphtho [2, 1-b] furan-2-carboxylates, aromatization, 1, 2- ...
