Procedure
The reaction was carried out similarly as described in the preparation of compound 101, using compound 407 (1.37 mmol) and compound 410 (1.62 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 20:80 to 35:65 as the eluent to afford the title compound as yellow foam. 13C NMR (DMSO-d6) δ 194.9, 158.7 (dd), 155.7 (dd), 149.4, 145.2, 139.8, 135.9, 133.7, 133.7, 131.7, 128.2, 127.1, 126.5, 126.5 (dd), 125.0, 124.2 (dd), 122.3, 114.8, 111.9 (dd), 111.8, 109.0, 105.0 (dd), 73.7, 65.8, 52.0, 26.4, 25.1, 19.4
