Asymmetric alkylation of a chiral α-amino alkenenitrile

Abstract
Alkylation of the unsymmetric allylic anion generated from 2-(L-ephedrino)-4-phenylbut-3-enenitrile occured exclusively at C-4 to give predominantly products having the 4R-configuration; the stereoselectivity increased remarkably when the reaction was conducted in a mixture of hexamethylphosphoramide and lithium iodide.
