Description and Uses
Menthyl acetate has a fresh odor similar to mint and rose (on dilution). It has a characteristic, fresh, pungent flavor, different from menthol (being much milder). It has a cool mouthfeel with only a trace of mint flavor. May be prepared by reacting acetic anhydride with menthol in the presence of anhydrous sodium acetate.
Menthyl acetate may be used in the preparation of 3-amino-2-hydroxyalkanoates via lithium amide-supported Mannich-type reaction of its lithium enolate with PMP-arylaldimines (PMP=p-methoxyphenyl) followed by in situ oxidation with oxaziridine.
