Description
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.
Chemical Properties
clear colourless to very slightly yellow liquid
Chemical Properties
3-Methyl-2-buten-1-ol has a phenolic, metallic odor bearing a resemblance to iron gallate ink
Uses
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.
Uses
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.
Definition
ChEBI: Prenol is an alkenyl alcohol and a member of prenols.
General Description
3-Methyl-2-buten-1-ol reacts with nitrosocarbonyl benzene to yield 5-hydroxy-isoxazolidines. It is commonly used as fragrance ingredient.
Flammability and Explosibility
Flammable
Synthesis
Prenol's two synthesis methods: 1) from Isoprene by hydration via Phenylacetate. 2) from Dimethyl vinylcarbinol with diluted Sulfuric acid.
