ABSTRACT:
The present invention relates to L-aspartyl-3-(bicycloalkyl)-L-alanine alkyl esters having high sweetness intensity, of the formula: ##STR1## wherein R.sup.1 is a substituted or an unsubstituted bicycloalkyl ring, said ring having 7 to 8 carbon atoms, the 2-position ring carbon atom is bound to the alamine 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.sup.2 is methyl. The "2R" configuration enantiomers of the R.sup.1 group are especially preferred. In preferred embodiments of the invention, R.sup.1 is a bornyl, camphanyl, norbornyl, 1-methylnorbornyl, 3-methylnorbornyl, 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.
