PROCEDURE

实验过程

The reaction was carried out similarly as described in the preparation of compound 102, using compound 103 (0.2 mmol). The crude product was purified by continuous gradient flash chromatography using EtOAc/petroleum ether (40-60) 50:50 to 100:0 as the eluent to afford the title compound as colourless foam. 13C NMR (CDCl3) δ 196.1, 159.2 (dd), 155.6 (dd), 148.0, 146.9, 139.9, 137.7, 135.3, 133.8, 131.9, 129.1, 128.0, 127.9, 126.4, 124.5 (dd), 124.3 (dd), 120.3, 116.3, 112.8, 111.6 (dd), 104.9 (dd), 58.8, 47.0, 32.6, 20.2
