Ugi post-condensation copper-triggered oxidative cascade towards pyrazoles
Beilstein Journal of Organic Chemistry, 2011 Pyrazolidinones were prepared in a two-step sequence starting from α-hydrazonocarboxylic acids. After a four-component Ugi coupling, the resulting hydrazone was engaged in a copper triggered [3 + 2] cycloaddition/aerobic oxidation cascade.

A Novel Strategy of Ugi-4CR/Huisgen 1,3-Dipolar Synthesis of 1H-1,2,3-Triazole-Modified Peptidoimetics [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 2018 In this protocol, we report a novel approach for the synthesis of a new class of heterocyclic 1H-1,2,3-triazole-modified peptidomimetic compounds. The process consists of an Ugi four-component condensation reaction of amines, an isocyanide, an aldehyde ...

Formation of Di-tert-butylurea from a Mononuclear Iron Tris(isocyanide) Complex
, 2016 We report the synthesis and characterization of the tripodal iron tris(isocyanide) complexes [TmR′Fe(CNR)3](OTf) (R = tBu, Ad; R′ = Me, Ph, Mes). These complexes generate the corresponding disubstituted ureas when treated sequentially with a reductant

Multicomponent synthesis of artificial nucleases and their RNase and DNase activity
Beilstein Journal of Organic Chemistry, 2011 The synthesis of new, artificial ribonucleases containing two amino acid residues connected by an aliphatic linker has been developed. Target molecules were synthesized via a catalytic three-component Ugi reaction from aliphatic diisocyanides ...
