General procedure: Tetrahydrobenzofurans and Annulated Dihydropyrans; General Procedure A mixture of 1,3-diketones 1,4, or 6 (0.25 mmol), nitroalkene 2 (0.275mmol, 1.1 equiv), catalyst A (0.5 mol%), and Ag2O (1 mol%) in CH2Cl2(2.5 mL, 0.1 M) was stirred at r.t. until the intermediate Michael ad-duct was completely converted as indicated by TLC. The crude prod-uct was directly subjected to flash chromatography on silica (n-pen-tane/Et2O or n-pentane/CH2Cl2) to afford the corresponding product3, 5, or 7.
