Acetic Acid → 1,3-Butanedione, 1-(2-furanyl)-

関与物質

反応手順

A mixture of methyl 2-furoate (23 g, 0.18 mole) and acetone (10.6 g, 0.18 mole) was slowly added to a stirred suspension of potassium tert-butoxide (41 g, 0.36 mole) in anhydrous toluene (300 ml) at 0° C. Upon standing overnight at room temperature, glacial acetic acid (22 ml, 0.36 mole) and then water (100 ml) were added. The organic layer was separated, combined with an ether extract of the aqueous phase, washed with water, dried, and distilled to give 1-(2-furyl)-1,3-dioxobutane: b.p. 66°-70° C./0.1 mm (18.5 g).
