Abstract
Nor-seco-type cucurbit[n]uril compounds and methylene bridged glycoluril oligomers are produced by reacting glycoluril and formaldehyde in strong organic or mineral acid at a temperature adequate to condense the reactants. These compounds are characterized by lacking —CH— groups rendering their internal cavities more open and, for example, more responsive to guest compounds.
