A general procedure is described for the synthesis of unsymmetrically substituted N-aryl-N'-alkyl (or aryl) 1,n-alkanediamines 1 (n = 2-5) by reduction of omega -alkyl (or aryl) aminoalkanamides 2 with borane. Compounds 2 are easily obtained by aminolysis of the corresponding omega -haloalkanamides 3.

Nucleophilic Substitution of Azide Acting as a Pseudo Leaving Group: One-Step Synthesis of Various Aza Heterocycles
The reaction of 3-azidopropanoic acid with the carbodiimide-based coupling reagent DIC leads to a six-membered-ring intermediate acting as a versatile precursor to a diverse set of aza heterocycles, including mono-, bi-, and tricyclic compounds.
