Abstract: PURPOSE: 2-Alkylcarbonylfuran is prepared by oxidizing a dienone compound with selenium dioxide CONSTITUTION: The compound if the formula (I) in which, R1 is H or C1-C10 alkyl; R2 and R3 are C1-C4 alkyl, respectively, or form together C1-C10 alkyl, alkoxy, C3-C8 cyclic compound which can be substituted with halogen, nitro, cyano, hydroxy, carboxyl or amino group; is prepared from the dienone compound. Thus, 7-methyl-5-methyl-3,5-octadien-2-one is dissolved in 1,4-dioxane and selenium dioxide is added thereto and stirred for 3 hours under nitrogen gas at 80°C to give 2-acetyl-4-methyl-5-isopropyl furan.

Abstract translation: 目的：2-烷基羰基呋喃通过用二氧化硒氧化二烯酮化合物来制备。该化合物如果其中R 1为H或C 1 -C 10烷基的式（I） R 2和R 3分别为C 1 -C 4烷基，或者可以被卤素，硝基，氰基，羟基，羧基或氨基取代的C 1 -C 10烷基，烷氧基，C 3 -C 8环状化合物。 由二烯酮化合物制备。 因此，将7-甲基-5-甲基-3,5-辛二烯-2-酮溶解在1,4-二恶烷中，向其中加入二氧化硒，并在氮气下在80℃下搅拌3小时，得到2-乙酰基 -4-甲基-5-异丙基呋喃。
