First claim

What is claimed:

R 1 is a five to six membered aromatic ring optionally having one to three heteroatoms selected independently from nitrogen, sulfur and oxygen or a bicyclic ring consisting of two fused partially saturated, fully saturated or fully unsaturated five to six membered rings, taken independently, optionally having one to four heteroatoms selected independently from nitrogen, sulfur and oxygen; and
said R 1 is optionally mono-, di-, or tri-substituted independently with cyano, halo, hydroxyl, amino, (C 1 -C 4 )alkyl, (C 1 -C 4 )alkoxy, (C 1 -C 4 )alkoxy(C 1 -C 4 )alkyl, hydroxy(C 2 -C 4 )alkoxy, carbamoyl(C 1 -C 4 )alkoxy, amino(C 2 -C 4 )alkoxy, cyano(C 1 -C 4 )alkyl, mono-N— or di-N,N—(C 1 -C 4 )alkylamino, aminocarbonyl, mono-N— or di-N,N(C 1 -C 4 )alkylaminocarbonyl, (C 1 -C 4 )alkylthio, aminosulfonyl, (C 1 -C 4 )alkylsulfinyl, (C 1 -C 4 )alkylsulfonyl, or mono-N— or di-N,N(C 1 -C 4 )alkylaminosulfonyl, wherein any of the (C 1 -C 4 )alkyl or (C 1 -C 4 )alkoxy may be optionally mono-, di- or tri-substituted with fluoro; or
wherein R 1 is optionally substituted with a five to six membered aromatic ring optionally having one to three heteroatoms selected independently from nitrogen, sulfur and oxygen;
R 2 is a fully saturated, partially unsaturated or fully unsaturated one to fourteen membered straight carbon chain wherein the carbons, other than the connecting carbon,
a. may be branched
b. may optionally be replaced with one or two heteroatoms selected independently from oxygen, sulfur and nitrogen, wherein said sulfur is optionally mono- or di-substituted with oxo,
