実験手順

(3R,3aS,6aR)hexahydrofuro[2,3-b]furan-3-yl N-((1S,2R)-1-benzyl-3-(cyclopentyloxy)[(3-hydroxyphenyl)sulfonyl]amino-2-hydroxypropyl)carbamate (0.09 mmol, 50 mg) was combined with 2-bromo-1-morpholino-1-ethanone (0.09 mmol, 18 mg) and potassium carbonate (0.26 mmol, 36 mg), and stirred in anhydrous DMF (1 mL) under nitrogen for 15 hours at room temperature. The reaction was concentrated to a residue, dissolved in ethyl acetate, washed in distilled water and brine, and dried over magnesium sulfate. The dried solution was then concentrated and purified by silica gel flash chromatography (1:1 hexanes/ethyl acetate) to provide 41 mg (67%) of a white solid. Rf=0.1 (1:1 hexanes/ethyl acetate); H1-NMR (CDCl3): δ 7.47 (2H,m), 7.38 (1H,m), 7.32-7.14 (7H,m), 5.64 (1H,s), 5.03(2H,m), 4.91-4.76 (1H,m), 4.78 (2H,s), 3.98-3.89 (2H,m), 3.89-3.77 (2H,m), 3.74-3.63 (8H,m), 3.63-3.52 (2H,m), 3.15 (1H,br.s), 3.08-2.98 (2H,m), 2.98-2.84 (3H,m), 2.84-2.74 (1H,m), 1.89-1.71 (4H,m), 1.71-1.49 (4H,m). MS (ESI): M+H=704.
