wherein R 2 and R 3 are each independently H, C 1-4 alkyl, aryl, or C 1-4 alkyl aryl;

wherein R 4 is H or C 1-4 alkyl; and

wherein R 5 is H or C 1-4 alkyl;

Q is a bond when W is absent, and is C 1-4 alkyl when W is present;

W is selected from H, C 1-4 alkyl, and C 2-6 alkenyl; where C 1-4 alkyl or C 2-6 alkenyl may be optionally substituted with C 1-4 alkyl, OH, OC 1-4 alkyl, NR 6 C(O)R 7 , CONR 6 R 7 , OR 6 , or NR 6 R 7 ;

wherein R 6 and R 7 are each independently H, C 1-4 alkyl, C 1-4 alkyl cycloalkyl, or aryl, and

Y is phenyl, optionally substituted with 0-3 substituents independently selected from halogen, C 1-4 alkyl, CF 3 , aryl, OH, OCF 3 , C 2-4 alkynyl, OC 1-4 alkyl, OC 2-5 alkylNR 9 R 10 , Oaryl, CONR 9 R 10 , C 1-4 alkylNR 9 R 10 , NR 11 C 1-4 alkylNR 9 R 10 , NR 9 COR 10 , NR 11 CONR 9 R 10 , and NR 9 SO 2 R 10 ;

wherein R 9 and R 10 are each independently H, C 1-4 alkyl, aryl, or C 1-4 alkyl aryl; and

wherein R 11 is H or C 1-4 alkyl.

2. A compound according to claim 1 or a pharmaceutically acceptable salt or diastereomer thereof, wherein:

W is selected from H, C 1-4 alkyl, and C 2-6 alkenyl; wherein C 1-4 alkyl or C 2-6 alkenyl may be optionally substituted with C 1-4 alkyl, OH, OC 1-4 alkyl, or NR 6 R 7 ;

wherein R 6 and R 7 are each independently H, C 1-4 alkyl, C 1-4 alkyl cycloalkyl, aryl;

Y is phenyl optionally substituted with 0-3 substituents independently selected from halogen, C 1-4 alkyl, CF 3 , aryl, OH, OCF 3 , OC 1-4 alkyl, OC 2-5 alkylNR 9 R 10 , Oaryl, CONR 9 R 10 , C 1-4 alkylNR 9 R 10 , NR 11 C 1-4 alkylNR 9 R 10 , NR 9 COR 10 , NR 11 CONR 9 R 10 , and NR 9 SO 2 R 10 ;

wherein R 9 and R 10 are each independently H, C 1-4 alkyl, aryl, or C 1-4 alkyl aryl; and

wherein R 11 is H or C 1-4 alkyl.

3. A compound selected from the group consisting of:

and pharmaceutically acceptable salts or diastereomers thereof.

4. A pharmaceutical composition comprising a carrier and at least one compound of claim 1 .
