2(5H)-Furanone Chemical Properties,Uses,Production
Chemical Properties
2(5H)-Furanone is light brown liquid
Occurrence
Reported found in coffee
Uses
2(5H)-Furanone is a versatile reagent used in Michael addition reactions1 for synthesis of lignans.2 Also employed in three-component Michael-Aldol reactions with an aldehyde anda thiolate3 or carbanion.4
Definition
2(5H)-Furanone is a mycotoxin that contains an α,β-unsaturated lactone moiety.
General Description
Chiral urea compounds catalyzed hetero-Michael addition reaction of 2(5H)-furanone (γ-crotonolactone) to pyrrolidine. The quorum sensing inhibition activity by 2(5H)-furanone was studied using bioindicator strains.
Hazard
Extremely toxic.
Purification Methods
Fractionally distil the lactone under reduced pressure. IR: (CCl4) 1784 and 1742 cm-1, UV no max above 205nm ( 1160 cm-1 M-1) and 1HR: (CCl3) : 2.15 (pair of triplets 1H), 3.85 (pair of triplets 1H) and 5.03 (triplet 2H).
