A series of new 4-aryl-1-(biarylmethylene)piperidines have been synthesized. They are structurally related to SLV-313, a potential atypical antipsychotic agent with potent D2receptor antagonist and 5-HT1Areceptor agonist properties. Suzuki-Miyaura reaction of cyclic vinyl boronates, derived from the vinyl triflates ofN-protected tetrahydropyridines, with appropriate aryl halides yielded 4-aryl- piperidines. The reductive amination of the latter with suitable biarylaldehdyes accomplished the synthesis of the new compounds.

Key words:Aryl-(biarylmethylene)piperidines, Suzuki-Miyaura Reaction, Reductive Amination, Schizophrenia

Since the reaction of amidrazones 1a – f and 4 can be described as a reaction between donor and acceptor, an increase of the donating ability would, of course, increase the yields

Firstly the formylating reagent triformamide ( 1b ) is generated from sodium diformamide ( 2 ) and methane- sulfonyl chloride in situ, which reacts with phenols 4a – f to give

In the present note we wish to report a new, even simpler method for the synthesis of aryl for- mates from phenols without isolating the formylating agent triformamide ( 1b )
