Patent ID: 7153869

Claim:
A compound of the formula: wherein: R 1 is the side chain of a natural or unnatural α-amino acid, where if said side chain contains a protectable group, that group may be protected with a member of the group consisting of succinyl, glutaryl, 3,3-dimethylglutaryl, C 1-5 alkyl, C 1-5 alkoxycarbonyl, acetyl, N-(9-fluorenylmethoxycarbonyl), trifluoroacetyl, omega-carboxyC 1-5 alkylcarbonyl, t-butoxycarbonyl, benzyl, benzyloxycarbonyl, 2-chlorobenzyloxycarbonyl, phenylsulfonyl, ureido, t-butyl, cinnamoyl, trityl, 4-methyltrityl, 1-(4,4-dimethyl-2,6-dioxocyclohexylidene)ethyl, tosyl, 4-methoxy-2,3,6-trimethylbenzenesulfonyl, phenylureido, and substituted phenylureido(where the phenyl substituents are phenoxy, halo, C 1-5 alkoxycarbonyl); R 2 and R 3 may be taken together to form a six-membered aromatic ring which is fused to the depicted ring, or are independently selected from the group consisting of hydrogen, C 1-5 alkyl, C 1-5 alkoxy, hydroxy, halo, trifluoromethyl, nitro, amino, phenyl, phenoxy, phenyl C 1-5 alkyl, phenyl C 1-5 alkoxy, substituted phenyl (where the substituents are selected from C 1-5 alkyl, C 1-5 alkoxy, hydroxy, halo, trifluoromethyl, nitro, cyano, and amino), substituted phenylC 1-5 alkyl(where the substituents are selected from C 1-5 alkyl, C 1-5 alkoxy, hydroxy, halo, trifluoromethyl, nitro, cyano, and amino), and substituted amino (where the substituents are selected from one or more members of the group consisting of C 1-5 alkyl, halosubstitutedC 1-5 alkyl, C 1-5 alknyl, C 1-5 alkenyl, phenyl, phenylC 1-5 alkyl, C 1-5 alkylcarbonyl, halosubstituted, C 1-5 alkylcarbonyl, carboxyC 1-5 alkyl, C 1-5 alkoxyC 1-5 alkyl, cinnamoyl, naphthylcarbonyl, furylcarbonyl, pyridylcarbonyl, C 1-5 alkylsulfonyl, phenylcarbonyl, phenylC 1-5 alkylcarbonyl, phenylsulfonyl, phenylC 1-5 alkylsulfonyl substituted phenylcarbonyl, substituted phenylC 1-5 alkylcarbonyl, substituted phenylsulfonyl, substituted phenylC 1-5 alkylsulfonyl, substituted phenyl, and substituted phenylC 1-5 alkyl[where the aromatic phenyl, phenylC 1-5 alkyl, phenylcarbonyl, phenylC 1-5 alkylcarbonyl, phenylsulfonyl, and phenylC 1-5 alkylsulfonyl substituents are independently selected from one to five members of the group consisting of C 1-5 alkyl, C 1-5 alkoxy, hydroxy, halogen, trifluoromethyl, nitro, cyano, and amino]); and W and Q is CH═CH.
