Anwendungen & Verwendung
Occurrence
Reported found in coffee, roasted filberts, tomato juice, raisin, roasted onion, French fried potato, crispbread, smoked fatty fish, boiled/cooked beef, fried cured pork, beer, cognac, rum, malt whiskey, cocoa, black tea, wild rice (Zizania aquatuca), and squid.
Verwenden
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.
