Branched amides of L-aspartyl-D-amino acid dipeptides

摘要

Amides of L-aspartyl-D-amino acid dipeptides of the formula (I) and physiologically acceptable cationic and acid addition salts thereof wherein Ra is CH2OH or CH2OCH3; R is a branched member selected from the group consisting of fenchyl, diisopropylcarbinyl, d-methyl-t-butylcarbinyl, d-ethyl-t-butylcarbinyl, di-t-butyl-carbinyl, 2-methylthio-2,4-dimethylpentan-3-yl, said amides are potent sweeteners having advantages over the prior art, edible compositions containing them, methods for their use in edible compositions and novel amide intermediates useful in their production.
