英文摘要: The synthesis and X-ray crystallographic characterization of diphenylglycoluril derivatives (1-4) that possess one or two alkyl groups on their N- or O-atoms is reported. Compounds 1-4 preferentially form linear hydrogen bonded tapes in the crystal by heterochiral recognition processes. We do not observe cyclic hydrogen bonded cucurbit[n]uril congeners that would result from homochiral recognition processes. The high propensity of alkylated derivatives of diphenylglycoluril to form hydrogen bonded tapes stands in stark contrast to the reported X-ray crystal structures of other known alkylated derivatives of glycoluril. We attribute this high propensity to form tapes to the phenyl and alkyl substituents that impart good solubility in non-polar aprotic solvents which do not compete for H-bonds. These results suggest that suitably functionalized glycoluril derivatives have untapped potential in studies of crystal engineering. (C) 2002 Elsevier Science Ltd. All rights reserved.
