Synthesis of a novel D-glucose-conjugated 15-crown-5 ether with a spiro ketal structure.
This paper describes a synthetic approach to a novel D-glucose-conjugated 15-crown-5 ether having a spiroketal structure starting from a 1-C-vinylated glucose derivative. The approach consists of the glycosylation of the vinylated glucose derivative to give an ethyleneoxy spacer derivative using bismuth(III) triflate, the conversion of the 1-C-vinyl group of the glucoside produced into a carbox...
متن کاملSynthesis and spectroscopic characterization of new Schiff bases containing the benzo-15-crown-5 moiety.
New crown ether Schiff base derivatives were prepared by the condensation of 4'-formylbenzo-15-crown-5 or 4'-formyl-5'-hydroxybenzo-15-crown-5 with 1,2-bis(2-aminophenoxy)ethane. The structures of these new compounds were confirmed on the basis of elemental analysis, IR, (1)H- and (13)C-NMR, UV-Vis and mass spectroscopic data.
متن کامل4′-Formylbenzo-15-crown-5
IN THE TITLE COMPOUND (SYSTEMATIC NAME 17-formyl-2,5,8,11,14-penta-oxabicyclo-[13.4.0]nona-deca-15,17,19-triene), C(15)H(20)O(6), the 15-crown-5 ring adopts a twisted conformation. The formyl group is coplanar with the benzene ring. The crystal packing is stabilized by C-H⋯O inter-actions involving the C=O group and ether O atoms as acceptors and methyl-ene CH groups as donors.
متن کاملF MRI of Fibroblasts and Neuroblastoma cells labeled with emulsified Perfluoro-15-Crown-5 Ether
Introduction: F-labelled cells provide an important new technique to evaluate in vivo the migration of implanted cells such as in stem cell therapy [1]. F-marker substances such as perfluorocarbons (PFC ) have been used for cell tracking based on F spectroscopy [2]as well as F magnetic resonance imaging (MRI). We present first results of F MRI of fibroblasts and neuroblastoma cells labeled with...
متن کاملPartial Molar Volumes of 15-Crown-5 Ether in Mixtures of N,N-Dimethylformamide with Water
The density of 15-crown-5 ether (15C5) solutions in the mixtures of N,N-dimethylformamide (DMF) and water (H2O) was measured within the temperature range 293.15-308.15 K using an Anton Paar oscillatory U-tube densimeter. The results were used to calculate the apparent molar volumes (VΦ ) of 15C5 in the mixtures of DMF + H2O over the whole concentration range. Using the apparent molar volumes an...
