Recent Advances in Palladium-Catalyzed Isocyanide Insertions
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.

Amide-Stabilized Enols in the Enol-Ugi Reaction: A Five-Component Synthesis of Triamides
In continuation with our research in the use of enols in multicomponent reactions with isocyanides (IMCR), for the first time we have used amide-stabilized enols as the acid component in enol-Ugi reactions.

Anodic oxidation of aminotetrazoles: a mild and safe route to Isocyanides [PDF]
A new electrochemical method for the preparation of isocyanides from easily accessible aminotetrazole derivatives has been developed, which tolerates an unprecedented range of functional groups. The use of chemical, rather than electrochemical, oxidation

On the reaction of diphenylketene with isocyanides
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 ...

Passerini and Ugi Reactions Involving Kinetically Unstable Isocyanides
International audienceKinetically unstable isocyanides as vinyl, allenyl and propargyl isocyanides react in Passerini and Ugi reactions faster than they decompose and lead to functionalized alpha-acyloxy amides and alpha-amino amides, respectively, which
