The asymmetric unit of the title compound, [Pd(2)Cl(2)(C(20)H(26)P)(2)]·2CH(2)Cl(2), contains one half-mol-ecule of the palladium complex and a dichloro-methane solvent mol-ecule. In the complex, two Pd(II) atoms are bridged by two Cl atoms, with the other two coordination sites occupied by a C atom of the biphenyl system and a P atom, resulting in a distorted square-planar coordination geometr...

A new optimal synthetic scheme for antibacterial compounds combining tris-(1-alkyindol-3-yl)methylium and 3-(indol-1-yl)maleimide in their structures was developed. The proposed method provided a significant increase the product yield, reduced labor intensiveness number of steps, used readily accessible starting reagents. Agood yield achieved 3-(formylindol-1-yl)-4-chloromaleimide, universal pr...

The reaction of the flavonol 3,7,3', 4'-tetra-O-methylquercetin (1) and of the isoflavone 7,4'-di-O-methylgenistein (2) with alkaline iodine in methanol afforded four new iodine derivatives: 8-iodo-5-hydroxy-3,7,3', 4'-tetramethoxy- flavone (1a) and 6-iodo-5-hydroxy-3,7,3', 4'-tetramethoxyflavone (1b) from 1; 2 afforded a mixture of two compounds, identified as a racemic mixture of (+/-)-trans-...

There is a great deal of interest in neurotrophin therapy to prevent neuronal degeneration. However, the blood-brain barrier presents a major hurdle in the use of peptide therapeutics. The goal of this study was to identify small molecule, cell-permeable nerve growth factor (NGF) activators. Combinatorial libraries of asterriquinones (>300) and mono-indolyl-quinones (>60) were screened using a ...

Five new compounds, including a benzopyran ribonic glycoside, daldiniside A (1), two isocoumarin ribonic glycosides, daldinisides B (2) and C (3), and two alkaloids, 1-(3-indolyl)-2R,3-dihydroxypropan-1-one (4) and 3-ethyl-2, 5-pyrazinedipropanoic acid (5), along with five known compounds (6-10), were isolated from the EtOAc extract of the marine-associated fungus, Daldinia eschscholzii. Their ...

Benzyltriphenylphosphonium bromide (BTPB) has been applied as an efficient catalyst for the preparation of bis(indolyl)methanes (BIMs) via electrophilic substitution of indoles with aldehydes in the absence of solvent.

Microwave assisted Diels-Alder cycloaddition of 5-Br-N-benzylpyridinone (2) with methyl acrylate is described to gain an easy access to 7-bromo-2-benzyl-3-oxo-2-aza-5 or 6-carbomethoxy bicyclo[2.2.2]oct-7-enes (3)-(6). The preparation of the ibogaine analogue 20-desethyl-(20-endo)-hydroxymethyl-11-demethoxyibogaine (17) is described by stereoselective hydrogenation of the C(7)-C(8) double bond....
