Isocyanide-based multicomponent reactions towards cyclic constrained peptidomimetics

open access: yesBeilstein Journal of Organic Chemistry, 2014
In the recent past, the design and synthesis of peptide mimics (peptidomimetics) has received much attention. This because they have shown in many cases enhanced pharmacological properties over their natural peptide analogues.

Poly(O‐Propargyl‐N‐Amino Carbamate), a Reactive Polymer to Underpin Biomedical Applications of Poly(acetylene)s

open access: yesMacromolecular Rapid Communications, EarlyView.
We report here a new methodology to prepare functional poly(acetylene)s under aqueous conditions. This methodology is underpinned by poly(O‐propargyl‐N‐amino carbamate) (P1), a reactive poly(acetylene) carrying acyl hydrazines. Thus, P1 reacts with aldehydes to give functional poly(acetylene)s, including cationic, hydrophobic, and sugar‐loaded poly ...

Diastereoselective Ugi reaction of chiral 1,3-aminoalcohols derived from an organocatalytic Mannich reaction

open access: yesBeilstein Journal of Organic Chemistry, 2016
Enantiomerically pure β-aminoalcohols, produced through an organocatalytic Mannich reaction, were subjected to an Ugi multicomponent reaction under classical or Lewis acid-promoted conditions with diastereoselectivities ranging from moderate to good ...

Electrochemical Decarboxylative Hydroxylation for the Sustainable Synthesis of Bempedoic Acid

open access: yesChemElectroChem, Volume 13, Issue 6, 17 March 2026.
A sustainable synthesis of bempedoic acid is achieved using electrochemical hydroxylative decarboxylation as the key step. Starting from Meldrum's acid, mild metal‐free alkylation, hydrolysis, and decarboxylation provide the key precursor, which is electrochemically converted to the alcohol intermediate and then hydrolyzed to the final product ...

Metal-Mediated Addition of N-Nucleophiles to Isocyanides: Mechanistic Aspects

open access: yesMolecules, 2017
Despite the long history of the investigation of nucleophilic addition to metal-bound isocyanides, some important aspects of the reaction mechanism remain unclear even for the simplest systems.

Base Metal Catalyzed Isocyanide Insertions [PDF]

open access: yesAngewandte Chemie, 2019
AbstractIsocyanides are diverse C1 building blocks considering their potential to react with nucleophiles, electrophiles, and radicals. Therefore, perhaps not surprisingly, isocyanides are highly valuable as inputs for multicomponent reactions (MCRs) and other one‐pot cascade processes.
