Uses
Glucose was transformed to various furan compounds and carboxylic acids derivatives by heat treatment of autoclave such as levulinic acid, 2-acetylfuran and 2-acetyl-5-methylfuran. using 2-acetyl-5-methylfuran or 1,5-dimethyl-2-pyrrolecarbonitrile as reactants, that the formation of the 4-arylation products. Reaction of 2-acetyl-5-methylfuran 6a with 2-aminoethanol pioduced in 79% yield the aminal.

General procedure for the synthesis of 5-methyl-2-acetylfuran from 2-methylfuran and ethanoic anhydride: continuous acylation of 2-methylfuran (2-MF) by acetic anhydride (AA) on parent Hb, AC-Hb, TA-Hb, Si-Hb zeolites in a fixed-bed reactor (Fig. 1) at atmospheric pressure. The reactor consisted of a glass tube (inner diameter 10 mm) and an electric heater. Before carrying out the acylation reaction, an equal amount of zeolite was activated for 2 h in a drying oven at 200 °C. The activated zeolites need to be transferred to the reactor immediately to avoid exposure to the atmosphere. In standard experiments, the acylation temperature was first controlled at 60 °C by a water bath. Subsequently, 5.9 g of zeolite catalyst was immobilized in the center of the fixed-bed reactor. A mixture of 2-MF and AA (molar ratio of 1:2.5 or 1:4) was delivered to the catalytic column via a metering pump at a set flow rate (0.07 mL/min). Liquid acylation products were periodically collected from the reactor outlet and quantitatively analyzed using a gas chromatograph (GC, Agilent 7890A) equipped with a flame ionization detector (FID) and a DB-FFAP capillary column (30 m length, 0.25 μm film thickness, and 0.25 mm diameter). The target product 2-acetyl-5-methylfuran (2-AC-5-MF) was obtained by acylation reaction and identified using a mass spectrometer (MS, Agilent 5975C) equipped with a mass selective detector.
