Aliphatic diamines react with N,N'-biscarbomethoxy-S-methylisothiourea (1) to give either heterocyclic or open chain products depending on the ease of formation of the ring systems.Thus, while 1,2- and 1,3-diamines form imidazolines and tetrahydropyrimidines respectively, 1,4-diamine forms only the bisguanidine.The polyamines form imidazolines and none of the possible larger heterocycles.
