| | 3-メチル-2-ブテン-1-オール Usage And Synthesis |
| 外観 | 無色～ほとんど無色透明液体 | | 用途 | 医薬品中間体,テルペン香料中間体 | | 説明 | 3-Methyl-2-buten-l-ol has a phenolic, metallic odor bearing a
resemblance to iron gallate ink. May be synthesized from isoprene
by hydration via prenyl acetate or by rearrangement of 3-methyll-buten-3-ol. | | 化学的特性 | clear colourless to very slightly yellow liquid | | 化学的特性 | 3-Methyl-2-buten-1-ol has a phenolic, metallic odor bearing a resemblance to iron gallate ink | | 使用 | 3-Methyl-2-buten-1-ol is used as a reagent for protection of carboxylic acids as their 3-methyl-2-buten-1-yl (Prenyl) esters. It is also used in perfumery. | | 使用 | 3-Methyl-2-buten-1-ol was used as starting reagent during asymmetric total syntheses of (R)-(+)- and (S)-(-)-umbelactone via Sharpless asymmetric epoxidation reaction. | | 定義 | ChEBI: Prenol is an alkenyl alcohol and a member of prenols. | | 一般的な説明 | 3-Methyl-2-buten-1-ol reacts with nitrosocarbonyl benzene to yield 5-hydroxy-isoxazolidines. It is commonly used as fragrance ingredient. | | 燃焼性と爆発性 | Flammable | | 合成 |
Prenol's two synthesis methods: 1) from Isoprene by hydration via Phenylacetate. 2) from Dimethyl vinylcarbinol with diluted Sulfuric acid.
