Isocyanides are important building blocks in organic synthesis; however, their synthesis is time and resource consuming often unpleasant due to smelly nature. Diversification of isocyanides can be accomplished by de novo or from already existing isocyanides. In this work, we report for the first-time isocyanide diversification based on nucleophilic aromatic substitution suitable precursor The m...

Novel sialidase inhibitors 11 having an α-acylaminoamido group at the C-4 position of Neu5Ac2en 1 against human parainfluenza virus type 1 (hPIV-1) were synthesized using one-pot isocyanide-based four-component condensation, and their inhibitory activities against hPIV-1 sialidase were studied. Compound 11b showed inhibitory activity (IC(50)=5.1 mM) against hPIV-1 sialidase. The degree of inhib...

The mol-ecule of the commercially available title compound, C9H9NO2S, has crystallographically imposed mirror symmetry, the mirror plane passing through the isocyanide group and the para-C atoms, the methyl C atom and the S atom of the methyl 4-tolyl sulfone moiety. In the crystal, C-H⋯O hydrogen-bond inter-actions link the mol-ecules into chains running parallel to the b axis.

Though the efficiency of isocyanides as strong ligands for transition metals was recognized very early, the disclosure of metal-catalyzed arylation of isocyanides has only been explored quite recently. In most of these studies, the formation of a metal/aryl complex starting from aryl iodide or bromide is followed by isocyanide insertion and trapping of the metal/imidoyl complex with various nuc...

In the title compound, [Fe(2)(C(7)H(4)IN)(C(3)H(6)S(2))(CO)(5)], the Fe-Fe distance of 2.5156 (11) Å compares well with that in related model structures. The phenyl isocyanide ligand is in the basal position and trans to the S atoms of the propane-dithiol-ate ligand due to steric hindrance. The crystal structure features C-H⋯O inter-actions.

Tungsten complex with a coordinated 2-azidoethyl isocyanide ligand reacts with PMe3 at the azido function to give a complex with a coordinated iminophosphorane which upon hydrolysis of the P=N bond yields a complex with an NH,NH-stabilized N-heterocyclic carbene ligand, 7; alkylation of the carbene ring nitrogen atoms gives a complex with an N,N'-dialkylated imidazolidin-2-ylidene ligand, 8 .

In the title compound, [FeBr(C9H9NO2S)(C30H30N2P2)][B(C6H5)4], the Fe(II) ion is in a distorted octa-hedral CBrN2P2 coordination geometry with a P-Fe-P angle of 109.95 (3)°. The relative orientation of the p-toluene-sulfonyl-methyl isocyanide ligand is defined by the C-S-C-N torsion angle of 67.1 (2)°. In the crystal, pairs of weak C-H⋯O hydrogen bonds connect the cations into inversion dimers,...

A simple and efficient strategy for the synthesis of indane-1,3-dione derivatives through a palladium(0)-catalyzed reaction incorporating tert-butyl isocyanide has been developed. In addition, by applying this protocol as the key step, indenopyrazole derivatives can be easily synthesized in high yields in a one-pot procedure. This methodology is tolerant of a wide range of substrates and applic...

The addition of 2,6-dimethylphenyl isocyanide (CN[DMeP], two equivalents) to previously reported (PNP)Sc(III) pyridyl complexes resulted in the formation of novel indoline complexes of scandium. By varying the nature of the pyridyl moiety one can intercept an intermediate prior to methyl migration. In addition to structural studies of two indolene complexes, we also propose a mechanism for the ...
