Reaction Steps

Compound 494 (0.039 g, 0.1 mmol) was suspended in dry CH2Cl2 (1 mL) under an argon atmosphere. K2CO3 (0.029 g, 0.21 mmol) was added followed by ethyl chloroformate (0.02 mL, 0.021 mmol). The suspension was stirred for 48 h at room temperature. Work up as described in the preparation of compound 277. The crude product was purified by flash chromatography using EtOAc/petroleum ether (40-60) 1:2 as the eluent. This afforded the title compound as oil. 13C NMR (CDCl3) δ 196.0, 159.1 (dd), 155.6 (dd), 153.7, 147.9, 139.5, 135.6, 135.1, 133.6, 132.6, 131.9, 129.1, 124.4 (dd), 124.3 (dd), 121.3, 119.8, 116.2, 112.7, 111.6 (dd), 104.9 (dd), 61.3, 19.7, 14.5
