Publikováno v: European Journal of Organic Chemistry. 2014:3773-3776
A practical sequence for the synthesis of optically active heteroaryl α-(hydroxyamino) esters was explored. The highly diastereoselective addition of heteroaromatics to a cyclic chiral nitrone allowed access to a series of heteroaryl hydroxylamines.

Publikováno v: ChemInform. 46
The highly diastereoselective addition of hetarenes to a chiral cyclic nitrone ((R)-II) followed by methanolysis, oxidation with Pb(OAC)4 and reaction with hydroxylamine produces a range of α-(hydroxylamino)esters in good yields and good enantiosele

Publikováno v: Tetrahedron. 56:791-804
The reaction of nitrones with various indole derivatives has been studied. When the reaction was promoted by ClSiMe3, the isolated products were 3,3′-diindolylalkanes. With HCl as the activating reagent, 3-indolylhydroxylamines were isolated. The d
