Abstract

We describe here the aminomethylation of chiral silyl enol ether derivatives using iminium ion. The choice of judicious precursors with adequate protecting groups for the silylation/ aminomethylation step was required to achieve the synthesis of β2-homotryptophane in few steps. The same methodology was used to prepare a β2-homolysine derivative.
