INTENSELY SWEETL-ASPARTYL-3-(BICYCLOALKYL)-L-ALANINE ALKYL ESTERSABSTRACT OF THE DISCLOSUREThe present invention relates to L-aspartyl-3-(bicycloalkyl)-L-alanine alkyl esters having high sweetnessintensity, of the formula:wherein R1 is a substituted or an unsubstituted bicycloalkylring, said ring having 7 to 8 carbon atoms, the 2-position ringcarbon atom is bound to the alanine moiety, the two carbonatoms of the ring that are vicinal to the 2-position carbon areeach substituted by a hydrogen or lower alkyl, the total numberof alkyl groups bound to the vicinal carbons is less thanthree, and R2 is methyl. The "2R" configuration enantiomers ofthe R1 group are especially preferred. In preferredembodiments of the invention, R1 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 beused for sweetening edible products such as foods andbeverages.
