In 2019,Organic Letters included an article by Haun, Graham; Paneque, Alyson N.; Almond, David W.; Austin, Brooke E.; Moura-Letts, Gustavo. Name: N-tert-Butoxycarbonylhydroxylamine. The article was titled 《Synthesis of Chromenoisoxazolidines from Substituted Salicylic Nitrones via Visible-Light Photocatalysis》. The information in the text is summarized as follows:
This effort reports the first redox-neutral visible-light photocatalytic intramol. dipolar cycloaddition for the diastereoselective synthesis of chromenoisoxazolidines. Alkenylphenyl nitrones with a diverse substitution pattern on the aromatic ring and the alkenyl substituent undergo visible-light-promoted cycloadditions in the presence of catalytic amounts of Ru(bpy)3Cl2 in high yields and selectivities. The proposed redox-neutral pathway is the predominant photoredox mechanism for this transformation. In the experimental materials used by the author, we found N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Name: N-tert-Butoxycarbonylhydroxylamine)
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Hydrogen peroxide (H2O2) and peroxy acids generally add an oxygen atom to the nitrogen of amines. With primary amines, this step is normally followed by further oxidation, leading to nitroso compounds, RNO, or nitro compounds, RNO2. Secondary amines are converted to hydroxylamines, R2NOH, and tertiary amines to amine oxides, R3NO.Name: N-tert-Butoxycarbonylhydroxylamine
