Page/Page column 29, (2008/12/05)
Compounds of formula (I) are inhibitors of p38 MAP kinase activity, and are useful in the treatment of, inter alia, inflammatory and autoimmune disease formula (I): wherein R3, R4, R5 and R6 are each independently hydrogen or halogen; M and P are independently -N= or -CH=; Z is (a) a radical of formula R1R2CHNH-Y-L1-X1-(CH2)Z-, wherein R1R2CHNH- is an N-linked amino acid or amino acid ester group as defined in the description, and -Y-L1-X1-(CH2)Z- is a linker radical as defined in the description.

o-Halosubstituted aromatic triazenes (e.g. I, Scheme 1) react with aryloxides (e.g. II, Scheme 1) in the presence of CuBr · Me2S, K2CO3 and pyridine in acetonitrile at reflux to afford biaryl ethers (e.g. V, Scheme 1). This general methodology (Tables 1 and 2) was applied to the construction of the C-O-D and D-O-E vancomycin model systems 37 (Scheme 2) and 50 (Scheme 3), demonstrating its potential in a projected total synthesis of vancomycin (1. Figure 1). For the construction of the vancomycin model AB biaryl ring system, a sequential strategy involving a Suzuki coupling of the C-O-D aryl iodide 74 (Scheme 7) and boronic acid 53 (Scheme 4), followed by macrolactamization was demonstrated, in which the preformed C-O-D ring framework served to preorganize the precursor for cyclization. The latter investigation led to Suzuki-coupling-based asymmetric synthesis of biaryl systems in which 2,2-bis(diphenylphosphino)-1,1'-binaphthyl (BINAP) was found to be the optimum ligand (Tables 3 and 4).
