Patent ID: 7939685

Claim:
A chiral compound of Formula III of at least about 50% enantiomeric purity wherein J is each R 6 is independently selected from the group consisting of halogen; NO 2 ; cyano; C 2 -C 5 alkoxycarbonyl; N(C 1 -C 4 alkyl) 2 ; CON(C 1 -C 4 alkyl) 2 ; C 1 -C 4 alkoxy; C 2 -C 5 alkylcarbonyloxy; C 2 -C 5 alkoxycarbonyloxy; optionally substituted phenylcarbonyloxy; tri(C 1 -C 4 alkyl)silyl; tri(C 1 -C 4 alkyl)siloxy; C 1 -C 4 alkyl optionally substituted with 1-3 phenyl rings; C 3 -C 6 cycloalkyl optionally substituted with C 1 -C 2 alkyl; adamantyl; a phenyl ring, or a 5- or 6-membered heteroaromatic ring, each ring optionally substituted; and when two R 6 are attached to adjacent phenyl ring carbon atoms, said two R 6 may be taken together with the phenyl ring to form a naphthalene ring system optionally substituted on either ring of said naphthalene ring system; each R 8 is independently selected from C 1 -C 4 alkyl, C 1 -C 4 alkoxy, halogen and nitro; each n is independently an integer from 0 to 4; and each q is independently an integer from 0 to 3.
