Electrochemical TEMPO-Catalyzed Oxidative Ugi-Type Reaction [PDF]
Oxidative isocyanide-based multicomponent reactions (oxidative IMCRs) are very useful tools for the rapid construction of molecular diversity starting from readily available and stable substrates. Despite all their benefits, such multicomponent reactions are underdeveloped and strictly limited to 3-component processes.

Unimolecular Exciplexes by Ugi Four-Component Reaction [PDF]
Exciplex or excited complex emission is an excited state process, arising from considerable charge transfer of an excited energy donor to an acceptor, which can be identified by the occurrence of a redshifted emission band that is absent in the ...

Synthesis of various N-heterocycles using the four-component Ugi reaction
Ugi 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.

Turn-Induction in Peptides Incorporating Novel Cyrene-Derived α,α-Disubstituted Amino Acid. [PDF]
Novel chiral cyrene‐derived Cyr residues were incorporated into peptides. The α,α‐disubstituted amino acid residue was introduced using the Ugi reaction. X‐ray crystallographic analysis of R‐ and S‐Cyr residues indicated preference to adopt left‐ and right‐handed α‐helical conformations, respectively.
