An efficient photocatalytic method was developed for the remote C5-H bond carboxylation of 8-aminoquinoline amide and sulfonamide derivatives. This methodology uses in situ generated ?CBr3 radical as a carboxylation agent with alcohol and is further extended to a variety of arenes and heteroarenes to synthesize the desired carboxylated product in moderate-to-good yields. The reaction proceeding through a single electron transfer pathway was established by a control experiment, and a butylated hydroxytoluene-trapped aryl radical cation intermediate in high-resolution mass spectrometry was identified.

Page/Page column 55, (2010/11/25)
The present invention relates to novel piperazine-piperidine compounds. The compounds are useful as 5-HT1A binding agents, particularly as 5-HT1A receptor antagonists and agonists. These compounds are useful in treating central nervous system disorders, such as cognition disorders, anxiety disorders, depression and sexual dysfunction.
