Polyaza macrocycles containing the piperazine ring as a semi-flexible moiety

Azamacrocycles 1-4 were synthesized from 9 in 20-30% overall yields. Compounds 1 and 2 extracted some metal ions into organic solvents, but 3 and 4 did not. The crystal structure of the Ag(I) complex of 1 has been determined.
