개요
α-Irone has a characteristic orris and violet-like odor. The commercially prepared product corresponds generally to the α-isomer.화학적 성질
Yellowish liquid; Soluble in alcohol. A mixture of three isomers (α-, βand γ-irone).출처
Reported found in orris root, raspberry and flowers of Pittosporum sp용도
Perfumery, violet odor. The α isomer is also used as a flavoring agent.제조 방법
By intramolecular thermal H-ene reaction of an allysilane.정의
ChEBI: A methyl ketone that is alpha-ionone in which a hydrogen at position 5 of the cyclohex-2-en-1-yl ring is substituted by a methyl group.일반 설명
Irone is a bioactive compound that is produced by an endophytic fungus in the rhizomes of Iris germanica.Synthesis
Alpha-n-Methy lionone is synthesized by condensation of Methylethyl ketone with Citral, and cyclization of the resulting Pseudomethylionone. Cyclization may be carried out with Boron trifluoride or other agent.Purification Methods
If large amounts are available, then fractionate through a Podbielniak column (p 10) or an efficient spinning band column, but small amounts are distilled using a Kügelrohr apparatus. The 4-phenylsemicarbazone has m 174-175o (165-165.5o).
