Reaction of aluminum azide with cyanoesters. Preparation of tetrazolo[1,5-c]pyrimidin-5(6H)-one and tetrazolo[1,5-c]quinazolin-5(6H)-one was written by Wagner, Eugene R.. And the article was included in Journal of Organic Chemistry in 1973.Name: Ethyl 1H-1,2,3-triazole-5-carboxylate This article mentions the following:
The reaction of Al(N3)3 with a variety of unsaturated β-cyano esters was studied. Both cis- and trans-3-cyanoacrylates gave trans-3-tetrazole-5-acrylate. trans-3-Cyanocrotonate gave trans-3-methyltetrazole-5-acrylate, while cis-3-cyanocrotonate gave a mixture consisting mainly of 1-(2-cyanopropenyl)tetrazolin-5(4H)-one and tetrazolo[1,5-c]pyrimidin-5-(6H)-one. The reaction of Al(N3)3 and Et o-cyanobenzoate gave a mixture of tetrazolo[1,5-c]quinazolin-5(6H)-one, 1-[o-(tetrazol-5-yl)phenyl]-tetrazolin-5(4H)-one, Et o-(5-tetrazolyl)benzoate, and o-(5-oxo-2-tetrazolin-1-yl)benzonitrile. The formation of the quinazolinone via a Curtius rearrangement is proposed. In the experiment, the researchers used many compounds, for example, Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7Name: Ethyl 1H-1,2,3-triazole-5-carboxylate).
Ethyl 1H-1,2,3-triazole-5-carboxylate (cas: 40594-98-7) belongs to triazole derivatives. Triazoles are important five-member nitrogen heterocycles involved in a wide range of industrial applications such as agrochemicals, corrosion inhibitors, dyes, optical brighteners, as well as biologically active agents. Triazole growth retardants such as uniconazole and paclobutrazol have been known to inhibit the biosynthesis of gibberellins by blocking kaurene oxidase, an P450 enzymeName: Ethyl 1H-1,2,3-triazole-5-carboxylate
