Abstract

An approach for the construction of benzotriazinone-triazole system is described. The synthesis is based on diazonium chemistry and subsequent intramolecular heteroatom-heteroatom bond formation. The introduction of triazole moiety occurred via click reaction catalyzed by nano-sized copper, supported on modified silica mesopore KIT-5 leading to the desired products in excellent yield. Also, in vitro acetylcholinesterase (AChE) inhibitory activities of the target compounds were screened by Ellman�s method. Figure not available: see fulltext. © 2016, Indian Academy of Sciences.
