Two macrocyclic chelating MRI agents (Gd-DO3A)3-TAB and (Gd-DO3A)2-DAB have been successfully synthesized by appending three and two Gd-DO3A moieties upon the acetylbenzene derivatives, respectively. The longitudinal relaxivity of (G

The relative orientation of chromophores is a key factor in determining the relationship between the structure and the functionality in molecular multichromophore ensembles. In the case of structurally flexible molecular systems in solution, the task to c

Novel arene-bis- and -tris(-oxoethanedithioate) esters of the benzene, the biphenyl, and, in particular, the naphthalene series were prepared by reaction of the corresponding diazoacetyl or bromoacetyl derivatives with elemental sulfur in the presence of triethylamine in dry DMF, and subsequent direct alkylation of the produced dithiocarboxylate anions. The thiolation reaction of the diazoketones was significantly promoted by the addition of anhydrous calcium chloride (calcium chloride-activated thiolation, or CAT). Certain carbonyl-activated methylene and methyl compounds exhibiting no bromo or diazo substituents could be also transformed into dithioesters by the CAT reaction. The structure of three dithioesters was corroborated by X-ray structural analyses. Copyright Taylor & Francis Group, LLC.
