3-Methyl-2-buten-1-ol

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.

clear colourless to very slightly yellow liquid

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.

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.

ChEBI: Prenol is an alkenyl alcohol and a member of prenols.

3-Methyl-2-buten-1-ol reacts with nitrosocarbonyl benzene to yield 5-hydroxy-isoxazolidines. It is commonly used as fragrance ingredient.

Flammable

Prenol's two synthesis methods: 1) from Isoprene by hydration via Phenylacetate. 2) from Dimethyl vinylcarbinol with diluted Sulfuric acid.
