Abstract

The following dipeptides possess a high order of sweetness: ##STR1## wherein X=O or S; PA1 R is alkyl containing 1-3 carbon atoms; PA1 R.sub.1 is cycloalkyl, cycloalkenyl, lower alkyl-substituted cycloalkyl or cycloalkenyl, bicycloalkyl, bicycloalkenyl, tricycloalkyl, cyclic ether, cyclic thioether, cyclic sulfoxides, cyclic sulfones, aryl, benzyl, alkylaryl, aromatic heterocyclic or alkyl substituted aromatic heterocyclic containing up to 10 ring carbon atoms and up to a total of 12 carbon atoms; PA1 R.sub.2, R.sub.3, R.sub.4 and R.sub.6 are each H or lower alkyl; PA1 R.sub.5 is H, lower alkyl or cycloalkyl containing 3-5 ring carbons; PA1 each n=0, 1 or 2; PA1 m=0 or 1; PA1 Z is an alkylene chain containing 0-2 carbon atoms in the principal chain and up to a total of 6 carbon atoms; PA1 and food-acceptable salts.
