Abstract
Chiral secondary amines of the 3,4-dimethoxyphenylethyl and the tryptamine system were reactedwith chiral acetylenic sulfoxides and achiral acetylenic sulfone. In the case of 3,4-dimethoxyphenylethylamine, much improved diastereoselectivity (96 : 4) was observed as compared to the reaction of achiralsecondary amine with chiral acetylenic sulfoxides.
Keywords
