Abstract
New regioselective reaction of 1-alkyl-5-hydroxy-4,5-diphenyl-1H-imidazol-2(5H)-one with alkylureas gives predominantly 1,6-dialkyl-3a,6a-diphenylglycolurils along with minor quantities of the 1,4-isomers. In case of propyl homologues, co-crystal of 1,6/1,4-dipropyl glycolurils would precipitate. Based on the analysis of the crystal packing of the products, new type of supramolecular chains for 1,4-disubstituted glycolurils has been identified.
期刊介绍：
Mendeleev Communications is the journal of the Russian Academy of Sciences, launched jointly by the Academy of Sciences of the USSR and the Royal Society of Chemistry (United Kingdom) in 1991. Starting from 1st January 2007, Elsevier is the new publishing partner of Mendeleev Communications.
Mendeleev Communications publishes short communications in chemistry. The journal primarily features papers from the Russian Federation and the other states of the former USSR. However, it also includes papers by authors from other parts of the world. Mendeleev Communications is not a translated journal, but instead is published directly in English. The International Editorial Board is composed of eminent scientists who provide advice on refereeing policy.
