Reaction Steps

Step 5) To a solution of compound 150 (500 mg, 0.87 mmol) in toluene (10.0 mL) was added p-TsCl (183 mg, 0.96 mmol) and the reaction mixture was heated to 90° C. for 12 h. The resulting mixture was diluted with EtOAc and washed with brine. The organic layer was dried over MgSO4, filtered, and concentrated in vacuo. The crude was purified by silica gel column chromatography to provide (2R,3R,4R,5S,6S)-2-(Acetoxymethyl)-6-(3-(4-ethylphenyl)-1,3-dihydroisobenzofuran-5-yl)tetrahydro-2H-pyran-3,4,5-triyl triacetate (151, 380 mg, 79%) as a yellow solid.
