Abstract
A simple three-component chiral derivatizing protocol for determining the enantiopurity of chalcogen amines by H-1, Se-77 and Te-125 NMR spectroscopy is described. The method involves the formation of a chalcogen-imino-boronate ester complex by the coupling of racemic chalcogen amines, 2-formylphenylboronic acid and optically active (+)-BINOL. The chalcogen primary amines were synthesized by a non active aziridine ring-opening reaction and chalcogen nucleophilic species. (C) 2016 Elsevier Ltd. All rights reserved. (AU)
