実験手順

To a solution of 7-(azidomethyl)-4-(3-fluorophenyl)-2H-chromen-2-one (30 mg, 0.1 mmol) and 1-ethyl-1-(trifluoromethyl)prop-2-yn-1-yl 4-nitrobenzoate (S-isomer, the second, slower eluting enantiomer from step 2) (27 mg, 0.1 mmol) in THF (5 mL) N,N-diisopropylethylamine (79 uL, 0.45 mmol) and copper iodide (26 mg, 0.14 mmol) were added. After overnight stirring, the reaction was diluted with ethyl acetate, filtered and washed with water and brine. The organic layer was then dried over MgSO4, filtered and concentrated. The crude residue obtained was purified by column chromatography (acetone/CH2Cl2 5:95) to afford the title compound. 1H NMR (400 MHz, acetone-d6): 8.5 (s, 1H), 8.42 (d, 2H), 8.31 (d, 2H), 7.7-7.6 (m, 1H), 7.51 (d, 1H), 7.4-7.25 (m, 5H), 6.42 (s, 1H), 5.89 (s, 2H), 3.1-2.98 (m, 1H), 2.91-2.8 (m, 1H), 1.14 (t, 3H).
