英文摘要	An efficient synthesis of functionalized 4H-chromenes by the tandem reaction of beta,gamma-unsaturated alpha-ketoesters with 2-naphthols, 1-naphthols, and 1,3-dihydroxynaphthalenes has been accomplished with high selectivity and excellent yields in the presence of a catalytic amount of bismuth triflate [Bi(OTf)(3), 5 mol%) under mild conditions. The functionalized 4H-chromene synthesis and our previous 2H-chromene hemiacetal synthesis could complement each other to enrich reaction diversity. (C) 2014 Hui-Jing Li and Yan-Chao Wu.
