Usage And Synthesis

Description

α-Methylbenzyl acetate has an intensive green odor suggestive of gardenia with a bitter, acrid taste, interesting on dilution. May be prepared by acetylation of methyl phenyl carbinol; from benzaldehyde by reacting with magnesium methyl bromide and subsequent acetylation; from 1-bromoethylbenzene and silver acetate in acetic acid.

Metabolism

Although no published data exist on the metabolism of methylphenylcarbinyl acetate, it is likely that hydrolysis to the carbinol and acetic acid is the initial step. Williams (1959) reports studies in which 50% of a dose of (±)-methylphenylcarbinol given to rabbits was excreted as the glucuronide in the urine within 24 hr. There was some evidence of oxidation and demethylation, as mandelic and hippuric acids were found in the urine. Previously, El Masry, Smith
