Preparation of 2,4-diphenyl-5,6,7,8-tetrahydro-1,6-naphthyridines was written by Campeanu, Valentin;Farcas, Sorin;Moraru, Mircea. And the article was included in Analele Universitatii Bucuresti, Chimie in 1998.Recommanded Product: 33439-27-9 This article mentions the following:
Michael addition of 1-methyl- and 1-(p-toluensulfonyl)-4-piperidones to chalcone afforded monocyclic 1,5-diketones, which were converted into the corresponding 6-substituted 2,4-diphenyl-5,6,7,8-tetrahydro-1,6-naphthyridines. Detosylation of the 6-tosyl derivative furnished the secondary amine. In the experiment, the researchers used many compounds, for example, 1-Tosylpiperidin-4-one (cas: 33439-27-9Recommanded Product: 33439-27-9).
1-Tosylpiperidin-4-one (cas: 33439-27-9) belongs to piperidine derivatives. Piperidine is a saturated organic heteromonocyclic parent, an azacycloalkane, a secondary amine and a member of piperidines. Piperidine derivatives are being utilized in different ways as anticancer, antiviral, antimalarial, antimicrobial, antifungal, antihypertension, analgesic, anti-inflammatory, anti-Alzheimer, antipsychotic and/or anticoagulant agents.Recommanded Product: 33439-27-9
