4-Methyl-5-(2-hydroxyethyl)thiazole (HCID 1136)

概要

5-(2-hydroxyethyl)-4-methylthiazole is a 1,3-thiazole that is thiazole substituted by a methyl group at position 4 and a 2-hydroxyethyl group at position 5. It has a role as a Saccharomyces cerevisiae metabolite, an Escherichia coli metabolite and a human metabolite. It is a primary alcohol and a member of 1,3-thiazoles. It is functionally related to a 5-(2-hydroxyethyl)-1,3-thiazole. It derives from a hydride of a thiazole.

用途有機合成原料。

説明4-Methy 1-5-thiazoleethanol has the characteristic disagreeable odor of thiazole compounds. It is somewhat pleasant and nut-like on extreme dilution. It may be prepared by reduction of ethyl- 4-methylthiazole-5-acetate using LiAlH4; by condensation of thioformamide with bromoacetopropanol or with y,y-dichloro-y,ydiacetodipropyl ether.

天然物の起源Reported found in grilled and roasted beef, cognac, brandy, Finnish whiskey, cocoa, peanuts, beans and malt.

使用5-(2-Hydroxyethyl)-4-methylthiazole has been used in the synthesis of novel thiazolium halogenide ionic liquids.

一般的な説明4-Methyl-5-thiazoleethanol is a sulfur-containing heterocyclic flavor compound that is reported to occur in Comté cheese and Panax ginseng.

調製方法

製造方法5-(2-Hydroxyethyl)-4-methylthiazole is prepared by reduction of ethyl-4-methylthiazole-5-acetate using LiAlH4; by condensation of thioformamide with bromoacetopropanol or with γ, y-dichloro-γ,γ-diacetodipropyl ether
