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;
R
1
, R
2
, R
3
, and R
4
are each independently selected from the group consisting of hydrogen and methyl;
X is selected from the group consisting of oxygen and nitrogen; and
R
5
is hydrogen or a C
1
-C
7
linear or branched acyclic hydrocarbon group, or R
