PROCEDURE

实验过程

To a solution of probucol (2.58 g, 5 mmol) in THF (50 ML) were added 4-hydroxybutyl acrylate (1.0 ml, 10 mmol), triphenylphosphine (2.62 g, 10 mmol) and diethyl azodicarboxylate (1.57 ml, 10 mmol). The resultant mixture was stirred under nitrogen at reflux over weekend. It was evaporated. Silica gel chromatography (hexanes/dichloromethane 4:1) gave the title compound as a brown oil (0.92 g). 1H-NMR (400 MHz, CDCl3): 7.54 (s, 2 H), 7.46 (s, 2 H), 6.42 (dd, 1 H), 6.14 (dd, 1 H), 5.84 (dd, 1 H), 5.38 (s, 1 H), 4.23 (t, 2 H), 3.75 (t, 2 H), 1.97 m, 2 H), 1.82 (m, 2 H), 1.46 (s, 6 H), 1.45 (s, 18 H), 1.42 (s, 18 H).
