Synthesis of new type of cephalosporin derivatives using ugi reaction
, 2015 Munkám során új típusú β-laktámokat hoztam létre négy komponensű Ugi reakcióval. Ezek után új laktám vázas molekulákat antibakteriális vizsgálatokon tanulmányozták.

Use of Ugi-three component reaction for the synthesis of poly(α-amino amide)s
, 2019 Multicomponent reactions (MCRs), in which three or more compounds react and form a product containing essentially all atoms of the starting reagents, have been thoroughly exploited in organic synthesis for preparing complex molecules.

Cyclic Imines in Ugi and Ugi-Type Reactions
ACS Combinatorial Science, 2020Ugi four-component reactions (U-4CRs) are widely recognized as being highly efficient for the synthesis of pseudopeptides. However, the products of these reactions are not so interesting as drug candidates because they are not conformationally restricted enough for a potent interaction with biological targets.

Insight into the Mechanisms of the Multicomponent Ugi and Ugi–Smiles Reactions by ESI‐MS(/MS)
European Journal of Organic Chemistry, 2014 AbstractThe mechanisms of the Ugi and Ugi–Smiles reactions were investigated by using finely selected reaction conditions that allowed all of the intermediates to be “fish‐out” and characterized by ESI‐MS/MS. New insight into the Ugi and Ugi–Smiles reaction mechanisms is provided without using charge‐tagged reagents.

A diastereoselective synthesis of pseudopeptidic hydantoins by an Ugi/cyclization/Ugi sequence
Tetrahedron, 2012Abstract A diastereoselective synthesis of helix-forming pseudopeptidic hydantoins by an Ugi 4CC/cyclization/reduction/Ugi 4CC sequence of reactions, giving mainly the l -adduct when benzoic acids were used, is described.

Recent Access to Polycycles via Post-Ugi Reactions
Processes, 2023 Ugi reactions have been widely studied due to their mild reaction conditions, high structural variability, and wide applications. Ugi adducts have proved to be highly efficient for different kinds of post-transformations by carefully choosing the ...
