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.
