摘要：
Enolate anions derived from 2-substituted 2-acyl-1,3-dithiane 1-oxides react readily with the nitrogen electrophile di-tert-butyl azodicarboxylate (DBAD) to give alpha-aminoketones with good diastereoselectivity and in reasonable yields; in some cases diastereoselectivity appears sufficiently high that the minor isomer cannot be detected by 400 MHz H-1 NMR spectroscopy.
