A newroute to tetrazole-derived cyclic amines based on the TMSN3-modified Ugi reaction with 2-substituted cyclic imines was elaborated. The reaction allows the direct preparation of five-, six-, and seven-membered cyclic amines substituted with a tetrazole ring, which are important types of organocatalysts. The scope and limitations of this method are discussed. In the case of the Ugi reaction with

The six‐component azido‐Ugi reaction with 2‐substituted 5–7‐membered imines leads to mono‐ or bis‐tetrazole derivatives depending on the starting imines. The reaction is very general regarding isocyanide structure and enables preparation of 1,5‐disubstituted bis‐tetrazole derivatives connected with 5–7‐membered cyclic amine fragments. Subsequent catalytic debenzylation provides the corresponding 1H‐tetrazoles

deazepanopyrrolo[1,2-c]imidazolidines has been developed. Annulation of acylethynylpyrroles with six- and seven-membered cyclic imines (MeCN/THF, 20–25 °C, 24–72 h) leads to tetrahydropyrrolo[1′,2′:3,4]imidazo[1,2-a]pyridines and hexahydropyrrolo[1′,2′:3,4]imidazo[1,2-a]azepines with (E)-acylethenyl moiety in 28–96% yields.
