A three-component electrophilic reaction transforms olefins into imidazoline and diamine derivatives. Rhodium(II) heptafluorobutyrate dimer (2 mol %) was utilized as the catalyst and N,N-dichloro-p-toluenesulfonamide (TsNCl ) and acetonitrile as the...

Passivation of the metal surface by dendrons bearing a focal 4-pyridone functionality (the second-generation dendron is shown; C: gray, N: blue, O: red) allows controlled nucleation and growth of gold...

Functionally protected forms of three conformationally constrained diaminodicarboxylic acids were synthesized and characterized. 2,2'-Diaminospiro[3.3]heptane-2,2'-dicarboxylic acid, an analogue of diaminopimelic acid, was prepared in racemic form and the structure established by...

The title methanol solvate, C(24)H(22)N(4)O(5).CH(3)OH, forms an extended three-dimensional hydrogen-bonded structure, assisted by the presence of several good donor and acceptor sites. It shows none of the crystal packing features...

The title compound, C(25)H(32)N(2)O(3), was synthesized as part of a series of related compounds using a modified Eschenmoser-Claisen rearrangement reaction. The compound is racemic and the structure features a centrosymmetric...

The structure of the title compound, a fentanyl derivative with formula C(36)H(36)N(3)O(3) (+)·Cl(-)·2CH(3)OH, crystallizes as a racemic mixture. The organic cation has an extended conformation and the structure displays O-H⋯O,...

The title compound, [Ni(C(32)H(33)N(3)O(3))], crystallized as a minor product during the purification of its 2(R)-pent-4-enyl diastereomer. Mixtures of the title compound and its enantiomer self-resolve.

The preparation, EPR spectra, and crystal structures of octaethyltetraphenylporphyrinatoiron(III) having two imidazole, N-benzylimidazole, and N-methylimidazole axial ligands are reported, [(OETPP)Fe(HIm)2]Cl, [(OETPP)Fe(N-BzIm)2]Cl, and [(OETPP)Fe(N-MeIm)2]Cl. Despite large variation in axial ligand size,...

[structure: see text] 1,10-Dimethylbicyclo[8.8.8]hexacosane (1) and 1,10-dihydroxybicyclo[8.8.8]hexacosane (2) were prepared in 4% yield over seven steps and in 18% yield over three steps, respectively, starting from 1,10-cyclooctadecanedione. The identities and...

Homo-ligated dirhodium(II) carboxamidates provide well-defined structural frameworks with which to investigate catalyst-controlled multiple asymmetric induction ("match/mismatch" effects). Diastereomeric pairs of methyl 2-oxoimidazolidine-4(S)-carboxylate ligands containing 2-phenylcyclopropane (4S,2'S,3'S-HMCPIM and 4S,2'R,3'R-HMCPIM) and N-benzenesulfonylproline...
