Abstract

A set of chiral β-seleno amines have been efficiently synthesized via the ring-opening reaction of chiral N-acyl oxazolidin-ones by selenium nucleophiles. These compounds could be transformed into β-seleno amides by reaction with acid chlorides. The present method is applicable to the synthesis of β-chalcogeno amides containing selenium, sulfur and tellurium atoms in good yields. Additionally, these new compounds were evaluated as ligands in the palladium-catalyzed asymmetric allylic alkylation, giving the corresponding alkylated products in up to 98% ee.
