A bis(disulfide)-linked offset cryptophane.
A new bis(disulfide)-linked offset dimer is formed from a dithiolated analogue of cyclotriguaiacylene. Unlike a similar tris(disulfide)-linked example, this is not a true cryptophane as the offset nature of the dimerisation and intramolecular host-guest interactions preclude its use as a host.
متن کاملChloride transport activities of trans- and cis-amide-linked bisureas.
Of the bisurea compounds linked through trans- and cis-benzanilide spacers, the cis-amide derivatives were found to be effective in chloride transport, using which a stimuli-responsive mobile carrier was devised.
متن کاملMorphological Control of Heteroleptic cis‐ and trans‐Pd2L2L′2 Cages
Control over the integrative self-sorting of metallo-supramolecular assemblies opens up possibilities for introducing increased complexity and function into a single self-assembled architecture. Herein, the relationship between the geometry of three ligand components and morphology of three self-sorted heteroleptic [Pd2 L2 L'2 ]4+ cages is examined. Pd-mediated assembly of two bis-monodentate p...
متن کاملDiastereomeric Xe chemical shifts in tethered cryptophane cages.
Cryptophane cages serve as host molecules to a Xe atom. Functionalization of cryptophane-A has permitted the development of Xe as a biosensor. Synthetic routes used to prepare cryptophanes result in racemic mixtures of the chiral cages. In the preparation of a tethered cryptophane-A cage for biosensor applications, some achiral and chiral substituents such as left-handed amino acids have been u...
متن کاملControlling cis/trans-selectivity in intramolecular Diels-Alder reactions of benzo-tethered, ester linked 1,3,9-decatrienes.
Predictions from DFT (B3LYP/6-31 G(d))-computed stereoisomer product distributions for intramolecular Diels-Alder (IMDA) reactions have been successfully replicated in the laboratory. Benzo-tethered hexadienyl acrylates generally undergo moderately trans-selective IMDA reactions which, as suggested by DFT calculation, arise from two opposing transition structure (TS) features: stabilising secon...
