Oximino-piperidino-piperidine-based CCR5 antagonists. Part 2: synthesis, SAR and biological evaluation of symmetrical heteroaryl carboxamides
摘要:
The synthesis, SAR and biological evaluation of symmetrical amide analogues of our clinical candidate SCH 351125 are described. A series of potent and orally bioavailable CCR5 antagonists containing symmetrical 2,6-dimethyl isonicotinamides and 2, 6-dimethyl pyrimidines amides were generated with enhanced affinity for the CCR5 receptor.

and cyanopyridines using B2 pin2 as an electron-transfer reagent. Complete regio- and cross-selectivity are observed when forming a range of valuable 2,4'-bipyridines. Phosphonium salts were found to be the only viable radical precursors in this process, and mechanistic studies indicate that the process does not proceed through a Minisci-type coupling involving a pyridyl radical. Instead, a radical-radical
