Publikováno v: Russian Journal of Inorganic Chemistry. 51:1900-1907

A statistical Monte Carlo computer simulation has shown that the use of a diphenylglycoluril fragment as a rigid linker should give bis(crown ethers) with identically oriented benzocrown rings located closely in space. The syntheses of the first repr

Study of conformation of cryptahemispherands by two-dimensional NMR spectroscopy

Autor: A. V. Bordunov, Yu. E. Shapiro, V. N. Pastushok, N. G. Luk'yanenko, A. R. Kalyuskii

Publikováno v: Chemistry of Heterocyclic Compounds. 29:343-348

Two-dimensional NMR spectroscopy (NOESY, COSY-DQF) has been used in a study of nitrogen-containing cryptahemispherands and their complexes with alkali metals. On the basis of experimentally established interproton distances, the preferred conformatio

Macroheterocycles. 51. Synthesis of macrocyclic polyamines in a biphasic system

Autor: V. N. Pastushok, L. K. Filonova, N. G. Luk'yanenko, N. V. Kulikov, S. S. Basok

Publikováno v: Chemistry of Heterocyclic Compounds. 26:346-349

Macrocyclic polyamines are conveniently synthesized by condensation of bissulfonamides with ditosylates or dibromides of glycols in the biphasic system toluene(xylene)-aqueous sodium hydroxide.

Publikováno v: ChemInform. 35

Two representatives of a novel class of cyclophanes containing two fragments of 2,7-dioxy-9H-fluoren-9-one bridged by triethylene glycol and p-xylyl linking units have been prepared. X-Ray analysis shows that the former has an anti-conformation and t
