In the title compound, [Pd(C11H13ClN)Cl(C8H7N)], which crystallized in the chiral space group P212121, the Pd(II) atom is coordinated by two C atoms, a Csp(2) atom of the 2-chloro-3-dimethyl-amino-1-phenyl-prop-1-en-1-yl ligand and a Csp atom from the benzyl isocyanide ligand, as well as an N atom of the ligand and a Cl atom, in a square-planar geometry. In the complex, there is a short C-H⋯Cl ...

A small family of structural analogues of the antimitotic tripeptides, hemiasterlins, have been designed and synthesized as potential inhibitors of tubulin polymerization. The effectiveness of a multicomponent approach was fully demonstrated by applying complementary versions of the isocyanide-based Ugi reaction. Compounds strictly related to the lead natural products, as well as more extensive...

Treatment of a dinuclear Ru(II) amido complex [Cp*Ru(mu2-NHPh)]2 (Cp* = eta5-C5Me5) with small organic substrates including CO, tert-butyl isocyanide, a sulfur ylide Ph2S=CH2, and diphenylacetylene resulted in an unexpected disproportionation reaction of the bridging amido ligands to produce a free amine and a series of imido-bridged diruthenium complexes [(Cp*Ru)2(mu2-L)(mu2-NPh)] (L = CO, t-B...

Marine isonitriles represent the largest group of natural products carrying the remarkable isocyanide moiety. Together with marine isothiocyanates and formamides, which originate from the same biosynthetic pathways, they offer diverse biological activities and in spite of their exotic nature they may constitute potential lead structures for pharmaceutical development. Among other biological act...

In the title compound, C17H18ClNO5, which was synthesized by reacting 4-chloro-3-formyl-coumarin, acetic acid and tert-butyl isocyanide, the acetamido side chain is convoluted with ring-to-side chain C-C-C-C, C-C-C-N and C-C-N-C torsion angles of -123.30 (14), -135.73 (12) and 176.10 (12)°, respectively. In the crystal, N-H⋯O and weak C-H⋯O hydrogen bonds are present, which together with π-π co...

At pH 7.0, ZOO, both in the absence and presence of phosphates, the time course of n-butyl isocyanide binding to deoxyhemoglobin is biphasic, and the two kinetic phases can be isolated spectrally and identified with the properties of the a and /3 chains. Under all conditions at this pH, both the association and dissociation rate constants of the p chains are at least 10 times larger than the co...

Various isocyanide-based multicomponent reactions prove to be highly reliable when ?-substituted ?-amino boronic esters are employed as the amine component, allowing efficient synthesis of unprecedented peptidomimetics and heteroatom-rich boron-containing small molecules. In particular, scope Ugi reaction is widely exploited, give a family enantiopure ?-amido boronates. The Ugi-azide van Leusen...
