The synthesis and conformational properties of glycophanes 2 3 (cyclodextrin−cyclophane hybrid receptors containing two maltose units linked by (4-hydroxymethyl) benzoic acid spacer) are described. binding in water these with a series 4-nitrophenyl glycosides α- β-configurations at the anomeric center have been studied using 1H NMR spectroscopy molecular mechanics calculations. A comparison those glycophane 1 (an α,α-trehalose glycophane) α-cyclodextrin (αCD) same shows existence stabilizing...
The complexation of copper(II)(from the perchlorate) by two tripodal ligands H2L bearing one pyridine and phenolic arms has been studied in co-ordinating solvents. One bears a MeS group at para position moieties. In presence triethylamine, only brown dimeric neutral complexes [(CuL)2] have obtained. absence base, green [Cu(HL)]+ were identified, which remains protonated. are reversibly interconverted upon addition acid or base. Some evidence is given supporting hypothesis protonation axial...
A direct correlation of the rate energy transfer in bridged bis-porphyrins (an example an phenanthroline-bridged bis-porphyrin is shown) with interchromophore distance indicated from time-resolved fluorescence measurements. The presence several starting conformations also revealed.

Abstract In view of the described results in acid‐induced polyepoxide cyclizations, biosynthesis fused polyether toxins may be better explained by a stepwise mechanism through oxonium ion intermediates acting on enzyme‐bonded precursor. A new synthetic strategy for regio‐ and stereospecific synthesis heterosubstituted oxolane oxane rings involving intramolecular iodoetherification 2,3‐epoxy‐cycloalken‐1‐ols was studied. Cyclization/solvolysis 2,3‐epoxy‐cycloalk‐5‐en‐1‐ols proceed with...
Abstract The trans‐epoxide (IVa), derived from the decatrienol (III), is treated with iodine in presence of tetrakis(isopropoxy)titanium to form monocyclic iodohydrin (V) and bridged tetrahydrofuran derivative (VI).

Abstract Treatment of the acetoxyepoxycyclononene (I) with phenylselenenyl iodide (II) gives a mixture iodotetrahydropyran (III) and dehydroiodinated derivative (IV) after hydrolysis.
