一般描述

3-Methyl-2(5H)-furanone (3-Methylfuran-2(5H)-one) has been synthesized in highest yield (77%) by employing α-methyl-γ- butyrolactone as starting reagent.

3-Methyl-2(5H)-furanone, a five membered conjugated lactone, is a volatile compound. Its synthesis has been reported. It is reported to be one of the predominant constituent of the flavor of pandan leaves. It is also found in Thai soy sauce, Arabica roasted coffee samples from Brazil, bio-oil from pine wood sawdust.

应用

3-Methyl-2(5H)-furanone is the suitable model compound used to investigate the fragmentation mechanism of five membered lactones by electrospray ionisation tandem mass spectrometry and also to study the airway irritation of isoprene, isoprene/ozone, and isoprene/ozone/nitrogen dioxide mixture.
