Ammonia in the tetrazole Ugi variation together with α-amino acid methyl ester-derived isocyanides provides tetrazolopiperidinones in good to high yields in one pot. The scope and limitations of this reaction were investigated by performing >70 reactions. The scaffold is useful to fill high-throughput screening decks and in structure-based drug design.

This review highlights structural and biosynthetic work on a group of nitrogen-functionalised terpenes that are almost exclusively found in marine invertebrates and the animals that feed on them. The chemical functionality reviewed includes isocyanides, isothiocyanates, formamides, thiocyanates, isocyanates, and dichloroimines. The literature through mid 2003 is reviewed and there are 143 citat...

Initial conditions disclosed for the Passerini-Smiles reaction are associated with a lack of efficiency that has prevented chemists from using it since its discovery. We wish to report herein our thorough study in the development of new experimental conditions for this coupling between electron-poor phenols, isocyanides, and carbonyl derivatives. These new conditions have been applied to severa...

A base-catalyzed tandem Michael addition/intramolecular isocyanide [3 + 2] cycloaddition of ethyl isocyanoacetate and Michael acceptors with tethered carbonyl groups is described. This reaction leads to the formation of fused oxazolines in a highly diastereoselective manner under very mild conditions.

A reaction between equimolar amounts of cis-[PdCl2(CNCy)2] (1) and indazole (HInd, 2) or 5-methylindazole (HInd(Me), 3) proceeded in refluxing CHCl3 for ca. 6 h affording the aminocarbene species cis-[PdCl2{C(Ind)=N(H)Cy}(CNCy)] (4) or cis-[PdCl2{C(Ind(Me))=N(H)Cy}(CNCy)] (5) in good (72-83%) isolated yields. Complexes 4 and 5 were characterized by elemental analyses (C, H, N), HR ESI(+)-MS, IR...

The adsorption of methyl isocyanide (CH3NC) and acetonitrile (CH3CN) has been studied on Pd(111). Methyl isocyanide adsorbs on Pd(111) at 80 K at low coverages with the isocyanide functionality oriented close to parallel to the surface; the surface-bound species reorients to a geometry in which the isocyanide group is perpendicular to the surface as the coverage increases. Desorbing the excess ...
