Procedure

In a argon stream, (1S,4R,5S,6S)-4,5,6-tris(benzyloxy)-3-(benzyloxymethyl)cyclohex-2-enol (0.5 g, 0.933 mmol) and triphenylphosphine (367 mg, 1.400 mmol) were added to a THF (6 mL) solution of 4-chloro-2-(4-ethylbenzyl)phenol (345 mg, 1.400 mmol) at room temperature. DIAD (0.276 mL, 1.400 mmol) was added thereto at the same temperature. The reaction mixture was stirred for 48 h. The reaction mixture was concentrated under reduce pressure, and the obtained residue was purified by prepared LC-MS to obtain 157 mg of ((1S,2S,3R,6R)-4-(benzyloxymethyl)-6-(4-chloro-2-(4-ethylbenzyl)phenoxy)cyclohex-4-ene-1,2,3-triyl)tris(oxy)tris(methylene)tribenzene (27).
