The mixture was refluxed for 1 h, cooled to r.t, and then n-Bu4N+I, 0.0032 g, 0.0089 mmol) and compound 10 (0.020 g, 0.688 mmol) in dry benzene (8 mL) were added. The mixture was stirred for 45 min at 10°C and quenched with H2O. After acidification with 2 M HCl, the mixture was extracted with EtOAc (3 x 10 mL, The organic phase was washed with brine, dried over Na2SO 4, filtered, and concentrated in vacuo. The residue was purified by flash chromatography on SiO2 (hexanes-EtOAc, 1:1) to afford the sporostatin (1, 0.017 mg, 95, as white solid, mp 198-200°C; [α]D25 -18.8 (c 0.5, MeOH, 1H NMR 300 MHz, DMSO, δ
