P. Molina et al., SYNTHESIS OF A NOVEL CLASS OF MACROCYCLIC-COMPOUNDS CONTAINING 1,3,4-THIADIAZOLE RINGS AS SUBUNITS, Journal of organic chemistry, 59(13), 1994, pp. 3665-3669
The synthesis and characterization of 12 new macrocycles containing tw
o, four, or six 1,3,4-thiadiazole rings as subunits are described. The
general methodology used is based on the nontemplated reaction of bis
(4-methyl-5-(methylthio)-1,3,4-thiadiazolium) diperchlorates with alph
a,omega-diamino compounds. Complexation properties of macrocycles 4a-4
c and 4e toward Ag+ are also reported.
