Aldimines, homoallylation, dienes

Homoallylation of Aldimines with Dienes Promoted by Diethylzinc. 195... 

The reaction is also applicable to a wide structural variety of 1,3-dienes, as demonstrated by the reaction of 2-furfural-p-anisidine imine (Table 9). All dienes react with the aldimine regioselectively at the diene termini bearing the highest electron densities and provide bis-homoallyl amines with excellent 1,3-syn diastereoselectivity. No C4-adducts are formed in these reactions.
