The Dimroth rearrangement of 1,2,3-triazoles in the synthesis of anion receptors based on calix[4]arenes

2004 ARKIVOC  
Dedicated to Professor Oleg N. Chupakhin on the occasion of his 70 th birthday (Abstract Reaction of tetrakis-(azidosulfonyl)calix[4]arenes with 2-cyanoacetamides afforded the product of the Dimroth rearrangement, namely tetrakis-(1,2,3-triazole-5-aminosulfonyl) calix[4]arenes. The complexation of the 1,2,3-triazolesulfonamide calixarene hybrids with anions was studied by NMR titration, and association constants were determined.
