5-Bromo-1-tetralone Chemical Properties,Usage,Production

Description

5-Bromotetralone is a synthetic intermediate useful for pharmaceutical synthesis.

Uses

5-Bromotetralone (5-Bromo-3,4-dihydro-2H-naphthalen-1-one) is a synthetic intermediate useful for pharmaceutical synthesis.

Synthesis Reference(s)

The Journal of Organic Chemistry, 49, p. 4226, 1984 DOI: 10.1021/jo00196a024

Synthesis

529-34-0

32281-97-3

68449-30-9

7-Bromo-3,4-dihydro-2H-1-naphthalenone and 5-bromo-1-tetrahydronaphthalenone were synthesized using 1-tetralone as starting material with reference to the methodology reported by Cornelius, L.A.M. and Combs, D.W. in Synthetic Communications 1994, 24, 2777-2788. The procedure was as follows: the isomers in the reaction mixture were separated by silica gel fast chromatography (using a Biotage Flash 75 system with an elution solvent ratio of 20:1 hexane/methyl tert-butyl ether) to afford 5-bromo-1-tetralone (11.59 g, 51% yield) and 7-bromo-1-tetralone (9.45 g, 42% yield), respectively.
