Polymacrocycles Derived via Ugi Multi‐Component Reactions
Macromolecular Rapid Communications, 2018AbstractThe synthesis of macrocycles based on the Ugi‐4CR has been thoroughly explored by Wessjohann and coworkers, while polymerizations utilizing the Ugi‐4CR are already patented by Ugi and recently studied more in detail, developing a new trend in polymer chemistry.

Homologation of Ugi and Passerini reactions using ynamides
Drug Discovery Today: Technologies, 2018Being important biological and pharmacological units, β-amino amides and β-acyloxy amides have a privileged position in both academia and industry. Developing a methods to prepare them has gained attention. Ynamides, which possess dual nucleophilic and electrophilic properties, are similar to isonitriles. In this review, usage of ynamides in the single

In the beginning of 2000s, at the Ural State Technical University, Yekaterinburg, there was developed a “combinatorial chemistry” laboratory training course for students specializing in biotechnology (Dr. M. Mironov). The aim of this laboratory course was to develop practical skills in the field of parallel synthesis and consolidate the lecture ...

New Antimycobacterial Leads from Multicomponent Hydrazino-Ugi Reaction
Medicinal Chemistry, 2015Previously, modification of isoniazide- and pyrazinamide-derived pharmacophores via the Ugi multicomponent reaction proved to be an effective strategy to obtain efficacious and non-cytotoxic antimycobacterial leads.To apply the hydrazino-Ugi reaction developed in our group toward modifying these pharmacophores with similar appendages as reported ...

Still Unconquered: Enantioselective Passerini and Ugi Multicomponent Reactions
Accounts of Chemical Research, 2018The Passerini three-component (P-3CR) and the Ugi four-component (U-4CR) are two of the most prominent isocyanide-based multicomponent reactions (IMCRs). The P-3CR transforms isocyanides, aldehydes (ketones), and carboxylic acids to α-acyloxy carboxamides, while the U-4CR converts isocyanides, aldehydes (ketones), amines, and carboxylic acids to α ...

Asymmetric phosphoric acid–catalyzed four-component Ugi reaction
Science, 2018Steering together all four Ugi pieces The nearly 60-year-old Ugi reaction is a remarkably efficient means of linking together four molecular building blocks: an aldehyde, an amine, a carboxylic acid, and an isocyanide. Because each component is independently tunable, the reaction is especially well suited to the assembly of ...
