化学的特性
5-Decanolide is a flavor constituent
of many types of fruit, cheese, and other dairy products. It is a colorless,
viscous liquid with a creamy-coconut, peach-like aroma.
天然物の起源
Reported found in rum, coconut, raspberry, apricot, bilberry, peach, strawberry, Swiss cheese, other cheeses,
butter, milk, milk powder, mutton fat, mango and nectarine.
使用
Used in pharmaceutical preparations, feed additive, flavorings agent. Also used by food and flavor industries for its coconut fragrance and taste. It is also used as a reagent in the synthesis of (±)-Massoilactone (M197600); a chemical component with antibacterial activity found in volatile oils.
製造方法
δ-Decalactone can be prepared by peracid oxidation of 2-pentylcyclopentanone.
(R)-δ-decalactone is obtained in high optical purity by starting from (R)-2-
pentylcyclopentanone . Hydrogenation or fermentation of
massoia lactone is also a practicable method to produce this
enantiomer.
A newer development for the preparation ofδ-decalactone describes a carboxylation
of 1-nonen-4-ol with carbon monoxide in the presence of a homogenous
palladium catalyst in an aqueous system.
定義
ChEBI: A delta-lactone that is 5-valerolactone substituted by a pentyl group at position 6.
一般的な説明
Measurement of optical rotatory dispersion and circular dichroism of (+) 5-decanolide (tetrahydro-6-pentyl-2
H-pyran-2-one) has been reported.
