One-Pot Synthesis of 纬-Azidobutyronitriles and Their Intramolecular Cycloadditions was written by Ivanov, Konstantin L.;Tukhtaev, Hamidulla B.;Tukhtaeva, Feruza O.;Bezzubov, Stanislav I.;Melnikov, Mikhail Ya.;Budynina, Ekaterina M.. And the article was included in Synthesis in 2020.Category: indole-building-block This article mentions the following:

Efficient gram-scale, one-pot approached to azidocyanobutyrates and their amidated or decarboxylated derivatives was developed, starting from com. available aldehydes and cyanoacetates. These techniques combine (1) Knoevenagel condensation, (2) Corey-Chaykovsky cyclopropanation and (3) nucleophilic ring opening of donor-acceptor cyclopropanes with the azide ion, as well as (4) Krapcho decarboxylation or (4′) amidation. The synthetic utility of the resulting 纬-azidonitriles was demonstrated by their transformation into tetrazoles via intramol. (3+2)-cycloaddition A condition-dependent activation effect of the 伪-substituent was revealed in that case. Thermally activated azide-nitrile interaction did not differentiate the presence of an 伪-electron-withdrawing substituent in 纬-azidonitriles, whereas the Lewis acid mediated (SnCl4or TiCl4) reaction proceeded much easier for azidocyanobutyrates. This allowed us to develop an efficient procedure for converting azidocyanobutyrates into the corresponding tetrazoles.
