Deprotonation with aluminum amides

Finally, a chiral triamine 35, derived from (-)-proline, has been used as the lithium salt for the deprotonation of amines (Section D.2.I.). It is obtained from A-benzyloxycarbonylproline by forming the amide with, .Ar,A -trimethyl-l,2-ethanediamine, cleavage of the protecting group, and lithium aluminum hydride reduction29.
