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 ...

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 ...

Synthesis of spiroindolenines through a one-pot multistep process mediated by visible light

Beilstein Journal of Organic Chemistry
Spiro-heterocyclic indolenines are privileged scaffolds widely present in numerous indole alkaloids. Here, we develop a novel approach for the one-pot multistep synthesis of different spiro[indole-isoquinolines].
