Nontemplate Synthesis of Two Novel 23-Membered N3O4-Donor Macrocycles
摘要:
[image omitted] A novel 23-membered heptadentate N3O4 Schiff base ligand has been prepared by [1+1] cyclocondensation of 1,2-bis(2'-aminophenoxy)-4-t-butylbenzene with 2,6-bis(2-formylphenoxymethyl)pyridine by a nontemplate procedure. Treatment of L1 with NaBH4 in EtOH/CHCl3 gave the di-amine macrocycle L2.
