    • Typical Procedure for Macrolactonization: Under argon, a solution of glycosidic acid 16 (150 mg, 0.22 mmol, PyS)2 (225 mg, 1.0 mmol, and Ph3P (303 mg, 1.2 mmol) in anhyd toluene (6 mL) was stirred for 6 h at r.t. The mixture was diluted with deoxygenated anhyd toluene (20 mL) and then was added dropwise by a syringe pump to refluxing anhyd toluene (280 mL) for 12 h. The solution was refluxed under argon for 7 d until the complete disappearance of 16 (judged by TLC analysis, The reaction mixture was concentrated under reduced pressure. The residue was subjected to silica gel column chromatograph (PE-EtOAc, 6:1) to afford the macrolides 17 (20 mg, 11, as a colorless syrup together with 18 (75 mg, 58, as a colorless syrup.
