Synthesis of pyrrole-fused dibenzoxazepine/dibenzothiazepine/triazolobenzodiazepine derivatives via isocyanide-based multicomponent reactions

Beilstein Journal of Organic Chemistry
An efficient and facile synthesis of pyrrole-fused dibenzoxazepine/dibenzothiazepine/triazolobenzodiazepine derivatives was developed through the isocyanide-based multicomponent reaction of isocyanides, gem-diactivated olefins, and cyclic imines such as ...

Synthesis of β‐ and γ‐Carbolinones Through a Fe(III)‐Mediated Radical 6‐Endo‐Trig Cyclization of Indole‐Based Ugi 4‐CR Adducts

European Journal of Organic Chemistry, EarlyView.
A practical strategy for synthesizing β‐ and γ‐carbolinones from indole‐based Ugi 4‐CR adducts through an intramolecular radical cyclization using Fe(III)–H species is presented. This approach enables the efficient synthesis of spiro‐carbolinones under mild reaction conditions and demonstrates the effectiveness of secondary radicals in both cyclization

Tetrasubstituted Imidazolium Salts as Potent Antiparasitic Agents against African and American Trypanosomiases

Molecules, 2018
Imidazolium salts are privileged compounds in organic chemistry, and have valuable biological properties. Recent studies show that symmetric imidazolium salts with bulky moieties can display antiparasitic activity against T. cruzi.

Counterion Effects in Decatungstate Photocatalysis

European Journal of Organic Chemistry, EarlyView.
Decatungstate photocatalysis is often discussed from an anion‐centered perspective, treating the counterion as a passive charge‐balancing species. This review highlights that counterion identity can instead profoundly influence catalyst solubility, ion pairing, aggregation, stability, substrate accessibility, and catalytic performance.

FeIII‐Mediated Synthesis of Azaspirodienones via Ipso‐Radical Cyclization of Ugi–4CR Adducts

European Journal of Organic Chemistry, EarlyView.
An efficient two‐step protocol for the synthesis of azaspirodienones via Fe‐mediated ipso‐radical cyclization of Ugi adducts has been developed. This methodology provides rapid access to these privileged spirocyclic architectures under mild conditions, offering a practical and versatile approach to generating structurally complex molecules with ...

Isocyanide-based multicomponent reactions towards cyclic constrained peptidomimetics

Beilstein 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.
