The present invention relates to novel derivatives of 1-alkyl-6-oxo-piperidine-3-carboxylic acids and 1-alkyl-5-oxo-pyrrolidine-3-carboxylic acids represented by Formula I:
wherein n is an integer of 1 or 2;
R1, R2, R3, and R4 are each independently selected from the group consisting of hydrogen and methyl;
X is selected from the group consisting of oxygen and nitrogen; and
R5 is hydrogen or a C1-C7 linear or branched acyclic hydrocarbon group, or R5 together with X form a 3- to 8-membered heterocyclic hydrocarbon group, and their uses as cooling compounds.
