Abstract
Two novel macrocyclic compounds 5S and 5A combining an 18-crown-6 and two cyclotriveratrylenes were synthesized by means of two methods from dibenzo-18-crown-6. The conformational isomers were separated using c omplexation with KSCN and their stereostructures were determined on th e basis of H-1 NMR spectroscopic and thermal equilibration studies.
