  • Process for the direct preparation of N,N-disubstituted derivatives for 4,13-diaza-18-crown-6
    Patent number: 4687844
    Abstract: A process for the direct preparation of N,N-di-substituted derivatives of 4,13-diaza-18-crown-6 in which the substituents on both nitrogen atoms are identical and derive originally from an amine, by reacting a 1,8-diiodo-3,6-dioxooctane or derivatives thereof in which the substituents are located on positions 1, 2, 4, 5, 7 or 8 or combinations thereof, with a molar equivalent of a primary amine in the presence of a base and solvent.
