Saturated and unsaturated compounds having sweet, salt or umami taste enhancement qualities. The compounds have the structure:
wherein R
1
═H or methyl;
R
2
is selected from the group consisting of H, C1-C4 alkyl, alkenyl and methylene;
R
3
is selected from the group consisting of H, C1-C8 straight or branched chain alkyl, alkenyl, dienalkyl and phenyl;
or if R
1
═H, R
2
and R
3
taken together can represent
cyclopropyl, cyclobutyl, cyclopentyl, cyclopentenyl, cyclohexyl, or cyclohexenyl;
R
4
is selected from the group consisting of H, methyl and ethyl;
R
5
is selected from the group consisting of H, methyl and ethyl;
R
6
is selected from the group consisting of H, C1-C9 straight or branched chain alkyl, alkenyl, alkyldienyl, and acyclic or cyclic containing no more than one ring;
with the proviso that in structure 1, when R
4
is H or Me and R
5
═H or methyl, R
6
may be selected from the group described above and phenyl.

Secondary and tertiary allylic alcohols can be converted to the corresponding allylically rearranged amides and acetates in presence of a catalytic quantity of cobalt(II) chloride and acetic anhydride in acetonitrile. Tertiary alcohols undergo complete rearrangement whereas the secondary ones yield a mixture of regioisomers.
