The present invention comprises compounds of Formula (I). Wherein: R1, R2, R4, J, Q, and A are as defined in the specification. The invention also comprises a method of preventing, treating or ameliorating a syndrome, disorder or disease, wherein said syndrome, disorder or disease is type II diabetes, obesity and asthma. The invention also comprises a method of inhibiting CCR2 activity in a mammal by administration of a therapeutically effective amount of at least one compound of Formula (I).
Amides and ketones are fluorinated or hydroxylated in HF-SbF5 in the presence of CCl4 or NBS, reaction occurring at a carbon far located from the functional group.
Reaction of cyclic ketones 2–6 and imines 15–17 in HF/SbF5 in presence of CCl4 yield hydroxy or fluoroderivatives, hydride abstraction occurring at a site located far from the functional group. Whereas ketones 2–5 yield only hydroxy derivatives, through cyclic carboxonium ion, imines 15, 16 N-protonated in the media conditions give only fluoroderivatives 18, 19, respectively, after quenching with HF–pyridine

dimethylaluminum N,O-dimethylhydroxylamine complex, is effective at masking reactivecarbonylgroups in situ from nucleophilic addition. This reagent allows chemoselective addition of reducing reagents, Grignard reagents, organolithiums, Wittig reagents, and enolates into substrates with multiple carbonylgroups. Moreover, the trapped carbonylgroup, a stable aminal, can be unmasked in situ for additional synthetic
