Synthesis of 1-aryl-tetralins and 4-aryl-benzopyrans by sulfoxide-mediated benzylic carbocation cyclizations was written by Volonterio, Alessandro;Zanda, Matteo. And the article was included in Tetrahedron Letters in 2005.Safety of 1-(3-Bromopropyl)-4-methoxybenzene This article mentions the following:
An alkylation/cyclization sequence, with both steps mediated by the ortho-N-methylformamido-phenylsulfinyl function, provided two new C-C bonds and an efficient entry to 1-aryltetralins and 4-arylbenzopyrans. Scope and limits of the process were studied in detail. In the experiment, the researchers used many compounds, for example, 1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3Safety of 1-(3-Bromopropyl)-4-methoxybenzene).
1-(3-Bromopropyl)-4-methoxybenzene (cas: 57293-19-3) belongs to organobromine compounds. Most of the natural organobromine compounds are produced by marine organisms, and several brominated metabolites with antibacterial, antitumor, antiviral, and antifungal activity have been isolated from seaweed, sponges, corals, molluscs, and others. The principal reactions for organobromides include dehydrobromination, Grignard reactions, reductive coupling, and nucleophilic substitution.Safety of 1-(3-Bromopropyl)-4-methoxybenzene
