Reaction Steps

A solution of benzofuran-7-carboxaldehyde (4.4 g) in dry dimethylsulphoxide was added dropwise to a stirred solution of sodium hydride (60% dispersion in oil, 2.5 g) and trimethylsulphoxonium iodide (7.6 g) in dimethylsulphoxide (50 ml) at room temperature. After 1 hour iced water was added and extracted with diethylether. The extracts were washed with water, dried, filtered and evaporated to a yellow oil. Chromatography on silica eluting with 10:1:90 ether:triethylamine:hexane gave 7-benzofuranyl oxirane as an oil.
