Semisynthesis of 6β-Acetoxyvouacapane Derivatives via the Ugi-Azide Multicomponent Reaction
Chemistry Proceedings, 2022 A semisynthesis of 6β-acetoxyvouacapane-1,5-disusbtituted tetrazoles derivatives from the leaves of Caesalpinia platyloba by using the Ugi-azide multicomponent reaction as a key step reaction is described. To our knowledge, this is the first report where

Recent Advances in Palladium-Catalyzed Isocyanide Insertions
Molecules, 2020 Isocyanides have long been known as versatile chemical reagents in organic synthesis. Their ambivalent nature also allows them to function as a CO-substitute in palladium-catalyzed cross couplings.

Selectivity in multiple multicomponent reactions: types and synthetic applications
Beilstein Journal of Organic Chemistry, 2019 Multiple multicomponent reactions reach an unparalleled level of connectivity, leading to highly complex adducts. Usually, only one type of transformation involving the same set of reactants takes place.

On the reaction of diphenylketene with isocyanides
Organic & Biomolecular Chemistry, 2005 The products obtained from the reaction of diphenylketene with a variety of isocyanides are shown to depend heavily on the concentration of diphenylketene; a high concentration results in the precedented dioxolane derivatives, at much lower concentrations the reactions follow an alternative course and polycyclic beta-lactams are generated by a cascade ...

Structure and Reactivity of Glycosyl Isocyanides
European Journal of Organic Chemistry, 2018 3D structural information was obtained from mono‐, di‐ and trisaccharide formamide and isocyanide derivatives by analysis of their X‐ray crystal structure and NMR spectroscopy. The isocyanide anomeric effect was observed. Data mining of the Cambridge Structural Database (CSD) was performed and statistically confirmed our findings.

Urea Synthesis from Isocyanides and O-Benzoyl Hydroxylamines Catalyzed by a Copper Salt
Molecules, 2022 In the presence of CuOAc, a series of unsymmetric ureas can be generated in moderate to good yields under mild reaction conditions (10 mol% of CuOAc, 2 equiv t-BuONa or PhONa, 30 °C), using aryl isocyanides and O-benzoyl hydroxylamines as the readily ...
