The present invention describes and claims compounds of the Structural Formula I, Structural Formula II, or Structural Formula III: wherein R
1
, R
2
, R
3
and R
3′
are —H or methyl, or R
3
and R
3
taken together form a double bond, or R
3′
is —H and R
2
and R
3
taken together form a spiro-cyclopropyl substituent, R
4
is —H or —F, and R5 is —H, methyl, —CI or —Br, Formula II wherein R
1
is —H, ethyl-, isopropyl-, cyclopropyl-, methyl- or methoxy-, R
4
is —H or —F, and “Y” is: (a) —CH
2
—; (b) —CR
6
H-0-CR
7
R
8
—, wherein R
6
, R
7
, and R
8
are independently —H or methyl; (c) —CR
6
H—N(R
9
)—CR
7
R
8
—, wherein R
6
, R
7
, and R
8
are independently —H or methyl; (d) —CH

)(R
10
)—C(R
7
)(R
8
)—, wherein R
7
, R
8
, R
9
and R
10
are independently —H or -methyl, or both R
7
and R
8
are —F, R
9
and R
10
are independently —H or -methyl, or both R
9
and R
10
are —F, or R
9
and R
10
taken together are (0=), which together with the carbon to which they are attached forms a carbonyl group.
