We report the late-stage functionalization of multisubstituted pyridines and diazines at the position α to nitrogen. By this process, a series of functional groups and substituents bound to the ring through nitrogen, oxygen, sulfur, or carbon are installed. This functionalization is accomplished by a combination of fluorination and nucleophilicaromaticsubstitution of the installed fluoride. A diverse
A compound of formula (I) N-oxides, addition salts, quaternary amines metal complexes stereochemically isomeric forms and metabolites thereof, wherein A is CR1 Or N; formula (A) or formula (B) D is H, C1-C6alkyl, C2-C6alkenyl, C2-C6alkynyl, G is NR10 or O Q is C1-C6alkyl, C2-C6alkenyl, C2-C6alkynyl, C3-C6Cycloalkyl, aryl or heterocyclyl; W is H, C1-C6alkyl, C3-C6Cycloalkyl, CH2F, CHF2 or CF3; one of X' and X" is H or CH3, the other is C1-C3alkyl, F, OH, NRaRb, CF3 or N3; or X' and X" are both F; Y is NRd or O; Z is O, NRa, CHRd, CF2 or S(=0)r or a bond; the other variables are as defined in the specification. The compounds of the invention are inhibitors of BACE and are among other things useful for the treatment and/or prevention of conditions associated with BACE activity such as Alzheimer's disease.
