Au-Catalyzed Formation of Functionalized Quinolines from 2-Alkynyl Arylazide Derivatives was written by Gronnier, Colombe;Boissonnat, Guillaume;Gagosz, Fabien. And the article was included in Organic Letters in 2013.SDS of cas: 33439-27-9 This article mentions the following:
A new method for converting 2-alkynyl arylazide derivatives into functionalized polysubstituted quinolines following a gold-catalyzed 1,3-acetoxy shift/cyclization/1,2-group shift sequence has been developed (e.g., I → II). This transformation proceeds under mild reaction conditions, is efficient, and tolerates a large variety of functional groups. In the experiment, the researchers used many compounds, for example, 1-Tosylpiperidin-4-one (cas: 33439-27-9SDS of cas: 33439-27-9).
1-Tosylpiperidin-4-one (cas: 33439-27-9) belongs to piperidine derivatives. Piperidine and its derivatives have become increasingly popular in many synthetic schemes. Some chemotherapeutic agents have piperidine moiety within their structure, foremost among them, vinblastine and raloxifene.SDS of cas: 33439-27-9
