Quinoline and isoquinoline dramatically increase the rate and yield of Fe‐ and Co‐catalyzed cross‐couplingreactions. This new catalytic process extends the scope of such cross‐couplingreactions to include complex functional groups and allows heteroaryl–heteroaryl bond formation to occur.

The synthesis of a family of farnesol analogues, incorporating aromatic rings, has been achieved in high yields through the development of a regioselective coupling of allylic tetrahydropyranyl ethers with organometallic reagents. The allylic THP group is displaced readily by Grignardreagents in the presence of Cu(I) halides but is stable in the absence of added copper. Thus, an allylic THP group

dichloropyridines with a range of functionalized (hetero)aromatic Grignard reagents at room temperature. Functional groups, such as esters and acetals, are well tolerated in this transformation. Previously challenging substrates, quinolines and isoquinolines, participate in the selective Cr‐catalyzed cross‐coupling in cyclopentyl methyl ether (CPME) as the solvent. The effective purging of Cr salts is demonstrated

Cyclic diamines of formula (I) or their pharmacologically acceptable acid addition salts, and their medical applications are described. These compounds inhibit the action of chemokines such as MIP-1a and/or MCP-1 on target cells, and are useful as a therapeutic drug and/or preventative drug in diseases, such as atherosclerosis, rheumatoid arthritis, and the like where blood monocytes and lymphocytes infiltrate into tissue.
Compounds of the formula (I)—shown below—are described.
The compounds are useful in the manufacture of a pharmaceutical composition for preventing or treating inflammatory diseases such as arthritis, psoriasis, asthma, or inflammatory bowel disease, disorders of respiratory function, gastrointestinal disorders such as functional bowel disease, functional GI disorders such as irritable bowel syndrome, functional diarrhoea, functional distension, functional pain, non-ulcerogenic dyspepsia or others associated with disorders of motility or secretion, urogenital tract disorders such as incontinence, as analgesics for treating pain including non-somatic pain, or as immunosuppressants to prevent rejection in organ transplant and skin graft.
