L-AMINODICARBOXYLIC-(0-CYCLOALKYL)-L-AMINOCARBOXYLATE ALKYL ESTERS, AN EDIBLE COMPOSITION CONTAINING SAME AS SWEETENERS AND A METHOD FOR SWEETENING AN EDIBLE COMPOSITION

摘要

Dipeptides of certain alpha -amino dicarboxylic acids and etherified hydroxy alpha -amino-mono-carboxylic acid esters posses a high order of sweetness. These dipeptides have the following formula: wherein R is alkyl containing 1-3 carbon atoms; R1 is cycloalkyl, cycloalkenyl, lower alkyl substituted cycloalkyl or cycloalkenyl, bicycloalkyl, bicycloalkenyl, tricycloalkyl, cyclic ether or cyclic thioether containing up to 10 ring carbon atoms and up to a total of 12 carbon atoms; R<2> and R<4> are each H or alkyl containing 1-3 carbon atoms; R3 is H, alkyl containing 1-6 carbon atoms or cycloalkyl containing 3-5 ring carbons; n = 0, 1 or 2; and m = 0 or 1; and food acceptable salts thereof. The novel compounds can be incorporated into an edible foodstuff as sweeteners.
