Perithiaden is from the Dibenzothiepin family of agents.
It is useful as sedative-neuroleptic, muscle-relaxant and sleep-promoting agent.[1]
This compound is very similar in structure to both Dothiepin (Dosulepin) as well as the related six membered ring system that called pimethixene (Mepithiathene) [314-03-4]. The relative rigidity of the piperidine ring as well as the olefinic bridge that can covalently bind to the receptor would both be expected to affect the activity. The SAR is also related to Pipethiadene.
Synthesis
[edit]
The Grignard reaction between Dibenzo[b,e]thiepin-11(6H)-one, PC73741 (1) and 4-Chloro-1-Methylpiperidine [5570-77-4] (2) gives the corresponding carbinol and hence PC14175795 (3). Acid catalyzed dehydration to the olefin completed the synthesis of Perthiaden (4). If desired, urethane formation and hydrolysis gives the secondary amine but is an additional step.
