Abstract
Amides of dipeptides of L-aspartyl-D-amino acids of formula < IMAGE > and their cationic and addition salts with physiologically acceptable acids where Ra is methyl, ethyl, n-propyl or isopropyl, R is a branched radical selected from the group comprising phenyl, diisopropyl carbinyl, d-methyl-t-butyl carbinyl, d-ethyl-t-butyl carbinyl, di-t-butyl carbinyl, 2-methylthio-2,4- dimethylpentane-3-yl < IMAGE > where at least one of the radicals R3, R4, R5 or R6 is alkyl having from 1 to 4 carbon atoms and the remainder are hydrogen or alkyl having from 1 to 4 carbon atoms, X is O, S, SO, SO2, C=O or CHOH, m is 0 or 1-4, n and p are each 0, 1, 2, or 3 and the sum of n + p is not greater than 3 and the sum of the carbon atoms in R3, R4, R5 and R6 is not greater than 6 and when R3 and R4 or R5 and R6 are both alkyl, they are then methyl or ethyl, < IMAGE > where one of the radicals R7, R8 or R9 is alkyl having from 1 to 4 carbon atoms and the remainder are hydrogen or alkyl having from 1 to 4 carbon atoms and the sum of the carbon atoms in R7, R8 and R9 is not greater than 6, m and q are the same or different and each has the values previously specified for m, < IMAGE > where each of the radicals R12 and R13 is methyl or ethyl or R12 is hydrogen and R13 is alkyl having from 1 to 4 carbon atoms, Z is O or NH and t is 1 or 2, < IMAGE > where w is 1-4, R14 and R16 are each alkyl having from 1 to 4 carbon atoms, R15 is H, OH, methyl or ethyl and the sum of the carbon atoms in R14, R15 and R16 is not greater than 6 and when R14 and R15 are both alkyl, then they are methyl or ethyl and < IMAGE > where R17 and R19 are alkyl having from 1 to 4 carbon atoms, R18 and R20 are H or alkyl with 1 or 2 carbon atoms, A is OH and B is H, OH or CH3 and when joined together A and B are < IMAGE > where the sum of the carbon atoms in R17, R18, R19 and R20 is not greater than 6 and when R17 and R18 or R19 and R20 are both alkyl then they are methyl or ethyl these amides are powerful sweeteners which have advantages over those in the prior art edible compositions containing these amides, methods for their use in edible compositions and new intermediate amines and amides useful for their production.
