5-PHENYL-1-PENTANOL Usage And Synthesis

Chemical Properties

clear colorless to pale yellow liquid

Chemical Properties

5-Phenylpentanol has a floral, carnation, rose-like odor.

Uses

5-Phenyl-1-pentanol was used in the synthesis of:

• methoxy and fluorine analogs of N-(piperidinyl)-1-(2,4-dichlorophenyl)-4-methyl-5-(4-pentylphenyl)-1H-pyrazole-3-carboxamide (O-1302)
• 2-[5-(4-iodophenyl)-pentyl]oxirane-2-carboxylic acid ethyl ester

Definition

ChEBI: 5-Phenyl-1-pentanol is an aliphatic alcohol.

Preparation

1) from Benzaldehyde by condensation with Butyraldehyde, followed by complete hydrogenation and reduction of the unsaturated aldehyde.
2) from Phenyl magnesium chloride and Ethylene oxide.
3) by reduction of Phenylpentenoic acid, ethylester.

General Description

5-Phenyl-1-pentanol undergoes oxidation in the presence of ceric ammonium nitrate to yield 2-benzyltetrahydrofuran.
