    • The present invention relates to novel compounds having sweet, salt or umami taste enhancement qualities. These compounds have the structure: where R1 is H or methyl; R2 is selected from the group consisting of H, C1-C4 alkyl, alkenyl; R3 is selected from the group consisting of H, phenyl, C1-C10 straight or branched chain alkyl, alkenyl, alkynyl, alkyldienyl, acyclic or containing no more than one ring, which contains no more than a total of five heteroatoms selected from F, O, S, N, and P; and if R1=H, R2 and R3 taken together can represent cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, or cyclohexenyl, which contains no more than two of each heteroatom selected from N, O, and S; or if R1, R2 and R3 taken together can represent one, or two aromatic rings, which contain no more than three of each heteroatom selected from F, N, S, and O. R4 is selected from the group consisting of H, methyl or ethyl; R5 is selected from the group consisting of H, methyl and ethyl; R6 is selected from the group consisting of H, C1-C9 straight or branched chain alkyl, alkenyl, alkyldienyl, acyclic or containing no more than one ring; except for in the case of structure 1 when if R4=H or methyl and R5=H or methyl, R6 as described above and phenyl; or when R4, R5, and R6 taken together can be equal to R7 is selected from the group consisting C1-C4 alkyl, or alkenyl.
