Typical procedure for preparation of esters and regeneration of iodosodilactone : A mixture of iodosodilactone (1.74 g, 6 mmol) and DMAP (733 mg, 6 mmol) in CHCl3 (50 mL) is stirred under refluxing in air for 1 h. Then, carboxylic acid (7 mmol), alcohol (611 mg, 5 mmol) and PPh3 (1.3 g, 5 mmol) are added in sequence. The mixture is refluxed for 4 h. The reaction is quenched with saturated sodium bicarbonate solution (30 mL). The aqueous layer is extracted with CH2Cl2 (50 mL×3). The combined organic layer is dried with Na2SO4, and concentrated to afford the crude product, which is purified by silica gel flash chromatography to give the corresponding ester.
The aqueous layer is acidified with 5 N HCl (pH < 7), and most of water is removed in vacuo to give the crude material. Conc. HCl (15 mL) is poured into the residue, and aq. 5.8% NaOCl soln. (35 mL) is added dropwise to the vigorously stirred mixture at room temperature. After the addition of NaOCl is complete, stirring is continued for a further 4 h. The precipitated white solid is collected by filtration, washed with H2O, diethyl ether, and acetone, and dried at room temperature to give 1.63 g of iodosodilactone in 94% recovery yield.
