Synthesis of Polycyclic Functionally-substituted Triazole- and Tetrazole-containing Systems
摘要:
Cycloaddition of organic mono- and diazides to the triple bond of propargyl esters of mono- and dicarboxylic acids gave rise to polycyclic 1,2,3-triazole-substituted carboxylates. Dipropargyl dicarboxylates with diazides afforded oligomeric products with alternating triazole and carboxylate fragments. Reaction of a dipropargyl ester with 5-azidomethyltetrazole furnished a tetracyclic system with alternating triazole and tetrazole rings.

Polynuclear noncondensed systems in which the azole rings are bound by urethane or carbamide fragments have been synthesized by the reaction of azole carboxylic acid azides with heterocyclic alcohols.
