실험 절차

To a stirred solution of 2-hydroxyhexadecanoic acid (0.54 g, 2.0 mmol) and (E,4S)-1-(benzyloxy)-1-oxooct-2-en-4-aminium chloride (0.28 g, 1.0 mmol) in CH2Cl2 (5 mL), Et3N (0.3 mL) and subsequently WSCI (0.57 g, 3.0 mmol) and HOBt (0.32 g, 2.0 mmol) were added at 0° C. The reaction mixture was stirred for 1 h at 0° C. and at room temperature for 1 day. The organic layer was washed with brine, dried over Na2SO4 and evaporated under reduced pressure. The residue was purified by column chromatography (CHCl3/MeOH 98/2). Yield 0.33 g (75%); [α]D−10.3 (c 0.5 CHCl3);
