Liu, Qing-Sheng,Gong, Shu-Ling,Ding, Yan,Chen, Yuan-Yin,Wu, Xiao-Jun
, p. 2385 - 2387 (2004)
A new molecular clip and its two alkylated derivatives, which are soluble in most of organic solvents, were prepared from hydroxymethylated diphenylglycoluril and catechol. The structure and conformation of these new clips were studied. Their binding properties for dihydroxybenzene were also studied with the aid of 1H NMR titration.

An improved and scalable synthetic route to chiral porphyrin cage compounds, which will be used as catalytic machines for the encoding of information into polymers, has been developed. The porphyrin cage was made chiral by introducing one or two nitro gro

Several new tetrabromo compounds based on diphenyl- and dimethylglycolurils were synthesized. Sequential treatment of these compounds with imidazole, methyl iodide, and sodium tetrafluoroborate gave their corresponding tetra imidazolium salts. Some of the

Page/Page column 33, (2008/06/13)
The invention relates to a method for preparing cucurbiturils. The method comprises reacting an oligomer consisting of 2 to 11 linked glycolurils or glycoluril analogues with one or more compounds selected from glycoluril, glycoluril analogues and/or olig
Synthesis, Conformational Analysis, and Binding Properties of Molecular Clips with Two Different Side Walls
Reek, Joost N. H.,Elemans, Johannes A.A.W.,Nolte, Roeland J. M.
, p. 2234 - 2243 (2007/10/03)
A new general route toward the synthesis of diphenylglycoluril clips with two different side walls starting from the new precursor 6b and the known compound 2b is described. A variety of clips are accessible in this way, some of them containing metal binding ligand systems, viz. phenanthroline, pyridine, salophen, and porphyrin for future applications as supramolecular catalysts. The physical and binding properties of the new clips are presented and discussed.
Binding features of molecular clips derived from diphenylglycoluril

The structure and binding properties of a series of receptor molecules based on the building block diphenylglycoluril are described. These receptors bind dihydroxy-substituted aromatic guests in chloroform solution by means of hydrogen bonding and π-π stacking interactions. IR difference spectroscopy shows that the hydrogen bonds are formed between the OH groups of the guest molecule and the π-electrons of the urea carbonyl groups present in the receptor. The structure of the complexes was further investigated by comparing the complexation-induced shifts in the 1H NMR spectra with the calculated shifts for a number of geometries of the host-guest complexes. These data demonstrate that the guest molecules are clamped within the cavity of the receptor.
