- Synthesis and spectral properties of macrocyclic compounds containing 1,3,4-thiadiazole moeties connected by a carbon-oxygen bridge
-
The syntheses of 1:1-macrocycles 3 (n = 1), unsymmetrical macrocycle 5 (m = 0, n = 1), 2:2-macrocycle 5 (m = n = 1 and 2), 3:3 macrocycle 7, and several open-chain ethereal compounds prepared from 2,5-dichloro-1,3,4-thiadiazole 1 and various polyethylene glycols dianions are described. Structural proofs are afforded by their mass and NMR spectral features. The quaternization studies of a few macrocycles with methyl iodide at elevated temperature furnished a diketo derivative 8 through a facile Hilbert-Johnson reaction.
