An attractive strategy for generation of α-aminoanionsfrom aldehydes with applications in synthesis of homoallylic amines is described. Aromatic aldehydes can be converted to α-aminoanionequivalents via amination with 2,2-diphenylglycine and subsequent decarboxylation. The in situ generated α-imino anions are highly reactive for Pd-catalyzed allylation, forming the corresponding homoallylic amines
