Abstract

A new class of molecular clips and two novel macrocyclic polyamines were synthesized in one-pot procedures from aliphatic­ amines, formaldehyde, and rigid bis(ethoxy­carbonyl)glycoluril. Apart from characterization of all reaction products by 1H NMR, 13C NMR, mass, and IR spectroscopy, a clip molecule and two macrocyclic cycloadducts were also studied by X-ray crystallography.
