Document Type and Number:
WIPO Patent Application WO/2010/003299
Kind Code:
A1
Abstract:
An organic compound and preparation method thereof, particularly a flavor enhancer and preparation method thereof, are disclosed. Its chemical name is 4-isopropyl-5,5-dimethyl-m-dioxan-2-one. It is prepared by the following method: starting from isobutyraldehyde, obtaining intermediate 2,2,4-thimethyl-1,3-pentanediol via self-aldol reaction of isobutyraldehyde, esterifying with formic acid to obtain 2,2,4-trimethyl-1,3-pentanediol bisformate, then transesterifying with dimethyl carbonate to obtain 4-isopropyl-5,5-dimethyl-m-dioxan-2-one. It is useful for enhancing the flavors of foodstuff, soap, toothpaste, cosmetic, cigarette, detergent and the like, such that the flavors could be more satisfied.
