Abstract
Sweeteners of the formula: ##STR1## and food-acceptable salts thereof, where the substituents are disclosed herein.
Claims79
A compound represented by the Formula:
- ##STR27## and food-acceptable salts thereof, including a food acceptable salt of N-L-aspartyl-D-alanine[.beta.(+)fenchyl]ester and a food acceptable salt of N-L aspartyl-2-methylalanine[.beta.(+)fenchyl]ester wherein
- A is hydrogen, and alkyl containing 1-3 carbon atoms,
- A' is hydrogen or alkyl containing 1-3 carbon atoms;
- alternatively
- A and A' taken together with the carbon atom to which they are attached form cycloalkyl containing 3-4 carbon atoms;
- Y is --(CHR.sub.2).sub.n --R.sub.1 or --CHR.sub.3 R.sub.4 ;
- R.sub.1 is a .beta.,.beta.-dialkyl cycloalkyl, a .beta.,.beta.'-dialkyl cycloalkyl, a .beta.,.beta.,.beta.'-trialkyl cycloalkyl, .beta.,.beta.,.beta.',.beta.'-tetraalkyl cycloalkyl on which the alpha substituent is hydrogen and wherein the cycloalkyl ring contains up to 6 ring carbon atoms and a total of 12 carbon atoms;
- with the proviso that when the double asterisked carbon is an asymmetric or chiral center, the configuration around said carbon is in the D form.
