Abstract

This invention relates to novel sweeteners of the formula: ##STR1## wherein A is hydrogen, alkyl containing 1-3 carbon atoms, hydroxyalkyl containing 1-3 carbon atoms, alkoxymethyl wherein the alkoxy contains 1-3 carbon atoms or --CO.sub.2 R in which R is alkyl containing 1-3 carbon atoms; PA0 A' is hydrogen or alkyl containing 1-3 carbon atoms; PA0 A and A' taken together with the carbon atom to which they are attached form cycloalkyl containing 3-4 carbon atoms; PA0 Y is --(CHR.sub.2).sub.n -R.sub.1 or --CHR.sub.3 R.sub.4 ; PA0 R.sub.1 is alkyl-substituted cycloalkyl, cycloalkenyl, bicycloalkyl or bicycloalkenyl containing at least one alkyl in the .beta.-position of the ring, up to 7 ring carbon atoms and up to a total of 12 carbon atoms; PA0 R.sub.2 is H or alkyl containing 1-4 carbon atoms; PA0 R.sub.3 and R.sub.4 are each cycloalkyl containing 3-4 ring carbon atoms; PA0 n=0 or 1; and PA0 m=0 or 1; PA0 and food-acceptable salts thereof.
