実験手順

(3,4,5-Tris-octadecyloxy-cyclohexyl)-methanol (283 mg, 308 μmol), 4-hydroxy-benzaldehyde (56 mg, 459 μmol), and triphenylphosphine (121 mg, 461 μmol) were dissolved in dehydrated THF (5.5 mL), DIED (93.3 μL, 472 μmol) was added, and the mixture was stirred for 40 minutes. 4-Hydroxy-benzaldehyde, triphenylphosphine, and DIED (each 153 μmol) were added, and the mixture was stirred overnight. Triphenylphosphine and DIED (each 306 μmol) were added, and the mixture was stirred for 2.5 hours. THF was evaporated, and 90% aqueous acetonitrile (6 ml) was added to the residue to allow crystallization. The crystals were collected by filtration and thoroughly washed with acetonitrile to give crude crystals of 4-(3,4,5-tris-octadecyloxy-cyclohexylmethoxy)-benzaldehyde. The crude crystals were purified by silica gel column chromatography (hexane:ethyl acetate=20:1) to give the object compound (130 mg, 127 μmol, 41%).
