3-(Trifluoromethylsulfonyloxy)-2,5-dihydrofuran-4-carboxylic acid methyl ester A solution of tetrahydrofuran-3-one-4-carboxylic acid-methyl ester (P. Dowd, S.-C. Choi, Tetrahedron 1991, 47, 4847) (2.88 g, 20 mmol) in dichloromethane (200 ml) is mixed at -78 C. with diisopropyl(ethyl)amine (3.96 ml, 23.2 mmol). After 10 minutes, trifluoromethanesulfonic acid anhydride (3.88 ml, 23.2 mmol) is slowly added in drops to it. The batch is warmed to room temperature, stirred for 2 hours and concentrated by evaporation. The residue is purified by column chromatography (SiO2) with ethyl acetate-hexane: 3.62 g (66%) of product. 1H-NMR (CDCl3): delta=3.85 (s, 3H), 4.80 (t, 2H), 4.92 (t, 2H).
57595-23-0 Methyl 4-oxotetrahydrofuran-3-carboxylate 14666564, aTetrahydrofurans compound, is more and more widely used in various fields.
