実験手順
A suspension composed of compound 26 (0.59 g, 1.60 mmol), compound 5 (0.42 g, 1.19 mmol); K2CO3 (0.23 g, 1.68 mmol) and chloroform (25 mL) was heated to reflux for 72 h, then cooled to ambient temperature. The solid was vacuum filtered and washed with chloroform (3×10 mL). The filtrate and the washings were combined and concentrated. The residue was subjected to column chromatography eluting with 0-10% methanol in dichloromethane. The un-reacted starting material 26 (0.39 g; 66% recovery) was recovered in the separation. A mixture of two diastereomers of the desired products 27, which were not separable in this step, was obtained (0.29 g, 28%) as a colorless, viscous oil: 1H NMR (500 MHz, CDCl3) δ 1.08 (d, 3H), 1.37 (m, 2H), 1.48-1.68 (m, 6H), 2.55 (m, 4H), 2.74 (br, 2H), 2.92 (m, 1H), 3.18 (m, 2H), 3.58 (m, 1H), 3.72 (m, 1H), 4.70 (m, 1H), 4.80 (br, 1H), 5.08 (m, 4H), 6.92 (m, 1H), 7.08 (m, 5H), 7.22 (t, 1H), 7.34 (m, 10H), 7.92 (s, 1H), 8.31 (s, 1H); m/z (ESI) 638 [C39H47N3O5+H]+.
