A series of unprotected spirocyclic β-prolines and β-homoprolines are prepared by Rh-catalyzed C-H insertion. The key intermediate, a Rh nitrenoid, is generated by the N-O bond cleavage of a substituted isoxazolidin-5-one. The reaction proceeds on a gram scale with a catalyst loading of as little as 0.1 mol %, affording spirocyclic β-amino acids that are otherwise difficult to obtain. The building blocks prepared in this work will likely find applications in medicinal chem. In the experiment, the researchers used many compounds, for example, N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3Quality Control of N-tert-Butoxycarbonylhydroxylamine)
N-tert-Butoxycarbonylhydroxylamine(cas: 36016-38-3) belongs to anime. Amines have a free lone pair with which they can coordinate to metal centers. Amine–metal bonds are weaker because amines are incapable of backbonding, but they are still important for sensing applications.While stronger than hydrogen bonds, amine–metal bonds are still weaker than both covalent and ionic bonds.Quality Control of N-tert-Butoxycarbonylhydroxylamine
