ChemInform Abstract
The phosphine induced α-addition of nitrogen nucleophiles to conjugated alkynoates represents a new regioselective mode for the preparation of dehydroamino acids. By the use of alkyl substituted propiolates competitive γ-addition or redox isomerization can also occur. The reaction conditions, mainly the phosphine, infuence the course of reaction.
