UsesGlucose 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.
DefinitionChEBI: A furan carrying acetyl and methyl substituents at the 2- and 5-positions respectively.
Taste threshold valuesTaste characteristics at 50 ppm: nutty, cocoa-like with toasted, bready nuance
General Descriptions-cis-trans isomerism of 2-acetyl-5-methylfuran was investigated by IR and NMR spectroscopy.
