Application

Corey-Nicolaou Macrolactonization1)

Typical Procedure:
To a stirred solution of the hydroxy carboxylic acid 1 (125 mg, 0.422 mmol) in dry CH2Cl2 (15 mL) is added triphenylphosphine (125 mg, 0.48 mmol) followed by 2,2’-dipyridyl disulfide (105 mg, 0.48 mmol) and the mixture is stirred until TLC (ethyl acetate : hexane = 2 : 3) shows complete loss of starting material (usually 0.5 h – 2 h). The mixture is concentrated in vacuo and dissolved in dry toluene (150 mL). To the solution is added 0.006M AgBF4 solution in toluene (1.2 mL) and the mixture is heated under reflux for 12 h. The mixture is cooled and solvents removed in vacuo. The residue is purified by flash column chromatography (acetone : CH2Cl2 = 0.5 : 99.5) to afford the desired lactone 2 (95 mg, Y. 81%).
