Participants

Reaction Steps

A stream of ozone at -40° C. is passed for 2 hours into a solution of 8.0 g (0.029 mol) of (R)-5-(methoxymethyl)-3-(6-ethenyl-1,2-benzisoxazol-3-yl)oxazolidin-2-one in 210 ml of dichloromethane, then the ozone is driven off with a stream of argon, and 10.7 ml (0.15 mol) of dimethyl sulphide are added. The mixture is stirred for 3 hours while allowing the temperature to return to ambient temperature, and then the solvent is evaporated off under reduced pressure. By chromatography of the residue on a silica column with a mixture of 30% ethyl acetate in cyclohexane, 5.0 g of product are obtained.
