| 摘要 |
The present invention relates to L-aspartyl-3-(bicycloalkyl)-L-alanine alkyl esters having high sweetness intensity, of the formula: <CHEM> wherein R<1> is a substituted or an unsubstituted bicycloalkyl ring, said ring having 7 to 8 carbon atoms, the 2-position ring carbon atoms is bound to the alanine moiety, the two carbon atoms of the ring that are vicinal to the 2-position carbon are each substituted by a hydrogen or lower alkyl, the total number of alkyl groups bound to the vicinal carbons is less than three, and R<2> is methyl. The "2R" configuration enantiomers of the R<1> group are especially preferred. In preferred embodiments of the invention, R<1> is a bornyl, camphanyl, norbornyl, 1-methylnorbornyl, 3-methynorbornyl, 7,7-dimethylnorbornyl, bicyclo [2.2.2] octyl, or pinanyl ring. The compounds of the invention, or edible salts thereof, can be used for sweetening edible products such as foods and beverages. |
