STRATEGY FOR THE SYNTHESIS OF UNSYMMETRICAL N-SUBSTITUTED POLYAZAMACROCYCLES
Gu, Kunjian,Mertes, Kristin Bowman,Mertes, Mathias P.
, p. 1323 - 1326 (1989)
A covergent route is described for the preparation of unsymmetrical N-substituted polyammonium macrocycles that is potentially applicable for the synthesis of a wide variety of macrocycles of differing ring size and heteroatom substitution.
