Abstract

Abstract 2-(Methylchalcogenomethyl) diphenyl selenoxides 1 and 2-{2′-(N, N- dimethylamino) ethyl} phenyl alkyl (or aryl) selenoxides 2, which were expected to be stabilized toward racemization by intramolecular coordination, were synthesized and optically resolved into their enantiomers on an optically active column using high- performance liquid chromatography. Relationship between the absolute configurations ...
