Candida antarctica lipase-catalysed double monoaminolysis of dimethyl malonate by (+/-)-trans-cyclohexane-1,2-diamine allows the sequential resolution of the latter compound, affording an enantiopure bis(amidoester), (R,R)-3, which is subsequently transformed into an optically active polyamine, (R,R)-9.
