摘要
Optically pure hetero-organic catalysts that bear a hydroxyl moiety, a stereogenic sulfinyl group, and a chiral amine moiety, are highly efficient in the asymmetric aziridination of unsaturated aldehydes and lead to the desired chiral products in high yields (up to 93%) with enantiomeric excess values up to 92%. The influence of the stereogenic centers at the sulfinyl sulfur atom and in the amine moiety on the stereochemical outcome of the title reaction is discussed.
