A Modular Synthesis of 4-Aminoquinolines and [1,3] N-to-C Rearrangement to Quinolin-4-ylmethanesulfonamides was written by Oh, Kyung Hwan;Kim, Jin Gyeong;Park, Jin Kyoon. And the article was included in Organic Letters in 2017.SDS of cas: 888329-88-2 This article mentions the following:
A copper-catalyzed regiocontrolled three-component reaction afforded diversified 4-aminoquinolines, e.g., I, using nitriles, diaryliodoniums, and ynamides. The C7-substituted regioisomers were formed regioselectively when meta-substituted phenyliodonium salts were used. [1,3] N-to-C rearrangement of the products to quinolin-4-ylmethanesulfonamides, e.g., II, and simultaneous deprotection of benzyl and sulfonamide groups were newly developed. Finally, antimalarial CK-2-68 was successfully prepared In the experiment, the researchers used many compounds, for example, 3-(Phenylethynyl)oxazolidin-2-one (cas: 888329-88-2SDS of cas: 888329-88-2).
3-(Phenylethynyl)oxazolidin-2-one (cas: 888329-88-2) belongs to oxazolidine derivatives. Oxazolidines are well known as key portions of bioactive molecules or precursors of chiral molecules, as well as established chiral auxiliaries. Chiral oxazolidines are widely used as chiral auxiliaries, chiral ligands, protecting and/or directing groups in a variety of asymmetric transformations, thanks also to their easy cleavage or their further elaboration possibilities.SDS of cas: 888329-88-2
