Raising the Diversity of Ugi Reactions Through Selective Alkylations and Allylations of Ugi Adducts [PDF]
Frontiers in Chemistry, 2019 We report here selective Tsuji-Trost type allylation of Ugi adducts using a strategy based on the enhanced nucleophilicity of amide dianions. Ugi adducts derived from aromatic aldehydes were easily allylated at their peptidyl position with allyl acetate in the presence of palladium catalysts.

Application of heterocyclic aldehydes as components in Ugi–Smiles couplings
Beilstein Journal of Organic Chemistry, 2016 Efficient one-pot Ugi–Smiles couplings are reported for the use of furyl-substituted aldehyde components. In the presence of these heterocyclic aldehydes, reactions tolerated variations in amine components and led to either isolated N-arylamide Ugi ...

Ugi Four-Component Reactions Using Alternative Reactants
Molecules, 2023 The Ugi four-component reaction (Ugi-4CR) undoubtedly is the most prominent multicomponent reaction (MCRs) that has sparked organic chemists’ interest in the field.

Protein-Templated Hit Identification via an Ugi Four-Component Reaction [PDF]
, 2020 Kinetic target-guided synthesis represents an efficient hit-identification strategy, in which the protein assembles its own inhibitors from a pool of building blocks via an irreversible reaction.

Q&A: What are pathogens, and what have they done to and for us?
BMC Biology, 2017 Microbes are found on us, within us and around us. They inhabit virtually every environment on the planet and the bacteria carried by an average human, mostly in their gut, outnumber human cells. The vast majority of microbes are harmless to us, and many

Architecturally diverse proteins converge on an analogous mechanism to inactivate Uracil-DNA glycosylase [PDF]
, 2013 Uracil-DNA glycosylase (UDG) compromises the replication strategies of diverse viruses from unrelated lineages. Virally encoded proteins therefore exist to limit, inhibit or target UDG activity for proteolysis.
