The double addition of organolithium compounds and allylzinc bromide to the imines prepared from (R,R)-1,2- diaminocyclohexane by condensation with aromatic and heteroaromatic aldehydes gave secondary diamines with high yields and diastereoselectivities apart for the reaction of 2-pyridinealdehyde derivative which occurred with low to moderate stereocontrol.
