McGrory, Rochelle; Faggyas, Reka J.; Sutherland, Andrew published an article in 2021, the title of the article was One-pot synthesis of N-substituted benzannulated triazoles via stable arene diazonium salts.HPLC of Formula: 574-98-1 And the article contains the following content:
A mild and effective one-pot synthesis of benzothiatriazine-1,1(2H)-dioxides I [R = Me, Bn, Ph, etc.] and 1,2,3-benzotriazin-4(3H)-ones II [R1 = H, 5-F, 7-CF3, etc.; R2 = H, cyclohexyl, Ph, etc.] was developed. The method involved the diazotization and subsequent cyclization of 2-aminobenzamides and 2-aminobenzenesulfonamides via stable diazonium salts, prepared using a polymer-supported nitrite reagent and p-tosic acid. The transformation was compatible with a wide range of aryl functional groups and amide/sulfonamide-substituents and was used for the synthesis of pharmaceutically important targets. The synthetic utility of the one-pot diazotizaton-cyclization process was further demonstrated with the preparation of an α-amino acid containing 1,2,3-benzotriazin-4(3H)-one. The experimental process involved the reaction of 2-(2-Bromoethyl)isoindoline-1,3-dione(cas: 574-98-1).HPLC of Formula: 574-98-1
The Article related to benzotriazinone preparation, aminobenzamide polymer supported nitrite diazotizaton cyclization, benzothiatriazine dioxide preparation, aminobenzenesulfonamide polymer supported nitrite diazotizaton cyclization and other aspects.HPLC of Formula: 574-98-1
