Typical Procedure for Radical Cyclization Strictly deoxygenated Ac2O (20 mL) was added to a mixture of manganese(III) acetate dihydrate (3.21 g, 12 mmol) and LiCl (365 mg, 8.6 mmol) under argon atmosphere, and the resulting suspension was stirred at r.t. for 15 min. Then, a solution of β-ketoester( 15, 1 g, 2.86 mmol) in deoxygenated Ac2O (20 mL) was added, and the mixture was stirred at reflux for 9 h, at which time TLC showed no starting material. The reaction mixture was cooled to 0°C, and then quenched with H2O (10 mL, After stirring for 10 min, t-BuOMe (120 mL) was added and the reaction mixture was stirred for an additional 10 min. The mixture was washed with H2O (10 x 30 mL) and brine (3 x 20 mL, The dried organic layer was evaporated and the residue was directly purified by flash chromatography (hexane-t-BuOMe, 7:3) to yield 22 0.82 g, 74, as a yellow syrup
