Synthesis of Amines from Norbornane Series
TLDR
In this paper, a synthetic procedure was developed for preparation of exo-oriented di- and tetraamines of the norbornane series by 1,3-dipolar cycloaddition to norbornene and norbornadiene of generated in situ diazomethane followed by reduction of arising pyrazolines catalyzed by Raney nickel.Abstract:

Some Peculiarities of Oxidation of 1-Carbamoyl-Substituted Hexahydro-1H-thieno[3,2-c]pyrazole-4,4-dioxides
TL;DR: New bicyclic derivatives of nitrosulfolane annelated with 1-pyrazoline were obtained by oxidation of 3-aryl-1-carbamoyl-6a-methyl-6-nitro-3a,5,6,6a]-tetrahydro-1H-thieno[3,2-c]pyrazole-4,4-dioxides as discussed by the authors.

Novel Access to Polyazamacrocycles: Non‐Template Cyclization of Terephthalaldehyde and Aliphatic Polyamines
TL;DR: In this article, non-template [2+2] condensation of terephthalaldehyde with bis(3-aminopropyl)amine and N,N'-bis(3-, n-bis(1,2)-diaminoethane leads to macrocyclic systems that can be reduced and derivatized further.
