| Abstract |
A Schiff base cryptand is synthesized in 65-75 and 20\% yield, respectively, via one-step [2 + 3] condensation of a flexible dialdehyde with tris(2-aminoethyl)amine in the presence and absence of template; a polyoxa-aza cryptand is synthesized in 75\% yield upon reduction of the Schiff base. |
