Four Novel 30-Membered Imine and Amine Macrocycles Derived fromOrtho-Aminophenyl Diamines
摘要:
Two novel macrocyclic tetra-imine-diphenol Schiff base (H2L1 and H2L2) were synthesized by [2+2] cyclocondensation of ortho-aminophenyl diamines [1,2-bis(2'-aminophenoxy)benzene (I) and 1,2-bis(2'-aminophenoxy)-4-t-butylbenzene (II)] with 2,6-diformyl-4-methylphenol. Two novel tetra-amine-diphenol macrocycles (H2L3 and H2L4) have been obtained by reduction of the imine analogs with NaBH4 in MeOH/CHCl3.
