摘要：

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.
