2(5H)-Furanone Chemical Properties,Usage,Production
Chemical Properties
Colorless to pale brown-yellow clear liquid
Chemical Properties
2(5H)-Furanone is light brown liquid
Occurrence
Reported found in coffee
Uses
2(5H)-Furanone is employed in the preparation of 5-substituted 2(5H) furanones (gamma-butenolides) catalyzed by bifunctional aminothiourea and aminosquaramide organocatalysts through direct aldol reaction with aromatic aldehydes. Further, it is used in the synthesis of lignans by Michael addition reactions. In addition to this, it is used in three-component Michael-Aldol reactions with an aldehyde and thiolate or carbanion.
Uses
2(5H)-Furanone is a heterocyclic organic compound that is used widely in the synthetic preparation of pharmaceutical goods.
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).
