Abstract: The present invention describes and claims compounds of the Structural Formula I, Structural Formula II, or Structural Formula III: wherein R1, R2, R3 and R3? are —H or methyl, or R3 and R3 taken together form a double bond, or R3? is —H and R2 and R3 taken together form a spiro-cyclopropyl substituent, R4 is —H or —F, and R5 is —H, methyl, —CI or —Br, Formula II wherein R1 is —H, ethyl-, isopropyl-, cyclopropyl-, methyl- or methoxy-, R4 is —H or —F, and “Y” is: (a) —CH2—; (b) —CR6H-0-CR7R8—, wherein R6, R7, and R8 are independently —H or methyl; (c) —CR6H—N(R9)—CR7R8—, wherein R6, R7, and R8 are independently —H or methyl; (d) —CH2—C(R9)(R10)—C(R7)(R8)—, wherein R7, R8, R9 and R10 are independently —H or -methyl, or both R7 and R8 are —F, R9 and R10 are independently —H or -methyl, or both R9 and R10 are —F, or R9 and R10 taken together are (0=), which together with the carbon to which they are attached forms a carbonyl group.
