US 4,571,345 A · 1,1-Diaminoalkane derived sweeteners

Abstract

Compounds of the formula: ##STR1## wherein n is 0 or 1, R is lower alkyl (substituted or unsubstituted), R' is H or lower alkyl, and R" is a branched alkyl, alkyl-cycloalkyl, cycloalkyl, polycycloalkyl (poly=2 or more, fused or non-fused), phenyl or alkyl-substituted phenyl, and physiologically acceptable cationic and acid addition salts thereof, which compounds are potent sweeteners. These derivatives of gem-diaminoalkanes are many times sweeter than sugar and are free from undesirable flavor qualities. Furthermore, they possess an unanticipated high degree of solubility compared with known synthetic sweeteners. In addition, the compounds possess high stability so that they can be used in all types of beverages and in conventional food processing. Sweetening compositions and sweetened edible compositions of these compounds are also provided.
