A procedure for the transition-metal-free three-component reaction of 1,3,5-triazines, diazo compounds and tert-butyl nitrite has been described. This reaction goes through tandem nucleophilic attack to generate synthetically important β-aminonitroso-α-diazocarbonyl compounds in moderate to good yields. This protocol is distinguished by the use of readily available starting materials, wide substrate

assemblies to be considered a standard reagent in organic synthesis they must first demonstrate the ability to catalyze increasingly complex transformations. Herein, we report a three-component Aza-Darzens reaction that generates N-phenylaziridines, catalyzed by a supramolecular host, that provides the stereoisomer opposite to the one generated in bulk solution (trans vs cis). This transformation constitutes
