摘要：

(Figure Presented) Getting round the (periodic) table: The enamine activation concept has been extended to the asymmetric addition of selenium-based compounds to aldehydes in an organocatalytic transformation that provides high reaction efficiency and stereocontrol (ee values ranging from 95 to 99%) with readily available chiral secondary amines. The chiral α-seleno aldehydes thus formed can be used as versatile intermediates. © 2007 Wiley-VCH Verlag GmbH &. Co. KGaA.
