Patent ID: 7368462

Claim:
A compound, including all enantiomeric and diasteriomeric forms and acceptable salts thereof, said compound having the formula: wherein R has the formula: —(L) x —R 3 R 3 is a unit chosen from: i) aryl units having the formula: ii) biphenyl units having the formula: each R 5 is independently a substitute for hydrogen; the index x is 0 or 1; each of the indices n is from 0 to 5; R 1 has the formula: —(L 1 ) y —R 4 R 4 has the formula: R 6 and R 7 are each independently chosen from: i) hydrogen; ii) C 1 -C 8 substituted or unsubstituted linear, branched, or cyclic hydrocarbyl; iii) C 6 or C 10 substituted or unsubstituted aryl; or R 6 and R 7 can be taken together to form a heterocyclic ring having from 3 to 8 atoms; the index y is 0 or 1; R 2 is a unit chosen from: i) hydrogen; or ii) C 1 -C 4 linear, branched, or cyclic alkyl; L and L 1 are linking units each independently having the formula: each R 10 is independently chosen from: i) hydrogen; ii) C 1 -C 6 substituted or unsubstituted linear, branched, or cyclic hydrocarbyl; iii) —CO 2 R 9 ; iv) —CN; two R 10 units on the same carbon are be taken together to form a carbonyl group; or two R 10 units from two adjacent linking units are taken together to form a double bond; R 9 is hydrogen or C 1 -C 4 linear, branched, or cyclic alkyl; the index z is equal to 1, 2, or 3; and each R 8 is independently chosen from: i) hydrogen; ii) C 1 -C 6 substituted or unsubstituted linear, branched, or cyclic hydrocarbyl; iii) —CO 2 R 9 ; iv) two R 8 units can be taken together to form a carbonyl group.
