    Notes: Summary In 16 essential hypertensives on a program of energy restriction (800 kcal/day) with and without simultaneous salt restriction, the effects on blood pressure and intracellular Na+ and Ca2+ in red blood cells were studied. A decrease in blood pressure and intracellular free Na+ and Ca2+ was only observed in the cases of simultaneous energy and salt restriction. The beneficial effect of weight reduction in hypertension thus depends on a diminished salt intake and is probably mediated by changes in intracellular free Ca2+.

    Description / Table of Contents: Directed Synthesis of Translationally Isomeric [3]-Catenanes1)In a multi-step reaction sequence the tetrahydroxymetacyclophane 12c is synthesized. Acetalisation with 1,25-dichloro-13-pentacosanone followed by nitration and reduction afforded the diamine 13c. By cyclization of this compound in 2-pentanol with sodium carbonate and sodium iodide under high dilution conditions the monomeric products 16, 17, and 18 are obtained in yields of 21.4, 7.7, and 0.9%, respectively. On the basis of mass, 13C NMR and 1H NMR spectra the structure of these compounds is discussed. Starting from the precatenane 16 the [3]-catenanes 25a, b,c and 26a, b, c are obtained in a multi-step reaction sequence. The structure of these compounds is confirmed by mass, 13C NMR, and 1H NMR spectroscopic investigations.

Dessen Cyclisierung in 2-Pentanol in Gegenwart von Natriumcarbonat und Natriumiodid unter Verdünnungsbedingungen ergibt die monomeren Cyclisierungsprodukte 16, 17 und 18 in Ausbeuten von 21.4. 7.7 und 0.9%. Die Struktur dieser Verbindungen wird anhand der Massen-, 13C- und 1H-NMR-Spektren diskutiert. In einer mehrstufigen Reaktionsfolge werden aus dem Prä-[3]-catenan 16 die [3]-Catenane 25a, b, c und 26a, b, c erhalten. Die Struktur dieser Verbindungen wird durch 13C-NMR, 1H-NMR- und massenspektroskopische Untersuchungen bewiesen.
