Reaction Steps
A solution of silver trifluoroacetate (124 mg, 0.56 mmol, 0.4 eq) in triethylamine (0.5 mL) is added at 0° C. to a stirred solution of (3R,6S)-[6-(2-diazo-acetyl)-tetrahydro-pyran-3-yl]-carbamic acid tert-butyl ester (380 mg, 1.41 mmol, 1.0 eq) in tetrahydrofuran (20 mL) and methanol (20 mL). After 1 hour stirring at room temperature, solvents are removed and the crude product is purified by column chromatography (silica gel, eluent: petroleum ether:ethyl acetate, 10:1 to 3:1, v/v) to afford (2S,5R)-(5-tert-butoxycarbonylamino-tetrahydro-pyran-2-yl)-acetic acid methyl ester as a white solid (200 mg, 52% yield).
