Procedure
The reaction was carried out similarly as described in the preparation of compound 116, using compound 448 (0.03 mmol) and but-3-yn-1-ol (0.06 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 30:70 to 100:0 as the eluent to afford the title compound. 13C NMR (CDCl3) δ 194.7, 157.3, 150.5, 146.2, 141.4, 138.1, 135.8, 134.6, 134.2, 132.5, 132.2, 126.5, 125.3, 122.1, 120.6, 120.1, 115.2, 115.0, 111.8, 61.5, 55.6, 28.6, 19.9
