Procedure

Compound 315 was dissolved in TFA:water (3:1, 8 mL) and stirred at RT for 1 h. The reaction mixture was concentrated in vacuo and purified by continuously gradient flash chromatography using EtOAc/petroleum ether (40-60)(v:v=1:2 to 100:0) as the eluent, affording the title compound as a yellow foam. 13C NMR (DMSO-d6) δ 189.3, 158.8 (dd), 155.7 (dd), 154.9 (d), 153.8 (d), 149.5, 133.5, 133.4, 127.8 (d), 126.5 (dd), 126.3, 124.1 (dd), 119.7 (d), 117.1 (d), 114.9 (d), 114.7, 112.0 (dd), 111.7, 105.0 (dd), 70.4, 69.8, 62.5
