New tricks of well-known aminoazoles in isocyanide-based multicomponent reactions and antibacterial activity of the compounds synthesized

Beilstein Journal of Organic Chemistry, 2017
The well-known aminoazoles, 3-amino-5-methylisoxazole and 5-amino-N-aryl-1H-pyrazole-4-carboxamides, were studied as an amine component in Ugi and Groebke–Blackburn–Bienaymé multicomponent reactions.

Novel postmodifications of the Ugi reaction

, 2016
In this thesis several novel postmodifiactions of regular Ugi-4CR products have been examined. Their scope and limitations were tested both by permutating the required functionalities around the Ugi scaffold and by synthesizing compound libraries for successful permutations. The following reactions were examined: 1.
