A small library of fifty-five adenosine peptide analogs was synthesized, under the Pilot Scale Library (PSL) Program of the NIH Roadmap initiative, from 2?,3?-O-isopropylideneadenosine-5?-carboxylic acid 2. The coupling of amine or sulfanilamide reactants to the free 5?-carboxylic acid moiety of 2, in automated solution-phase fashion, led after acid-mediated hydrolysis to target compounds 3-57 in good yields and high purity. No marked anticancer or antimalarial activity was noted on preliminary cellular testing. Initial screening through the MLPCN program, however, indicates that these analogs may show diverse and interesting biological activities.

The photochemical behavior of bicyclo[2.1.1]hexyl derivatives was investigated by irradiation with a 450 W medium-pressure mercury lamp in acetonitrile solution. The irradiation of methyl bicyclo[2.1.1]hexane-5- carbonylbenzoate (1a) led to both Norrish type II cyclization and cleavage products with a molar ratio of 1:2.2, whereas the irradiation of methyl 5-methylbicyclo[2.1.1]hexane-5-carbonylbenzoate (1b) afforded the only Norrish/Yang photocyclization compound as the sole product. Such results were illustrated by several geometric parameters for Norrish/Yang photoreaction as phi1, phi4 and beta obtained from the crystal structures. Furthermore, asymmetric photochemical studies using ionic chiral auxiliary technique were also conducted in the solid state. Bicyclo[2.1.1] hexanyl derivatives were synthesized and their photochemical behaviour was investigated in acetonitrile solution. Copyright

Dibromobis(2,4-dimethylpyridine)cobalt(II) (1) crystallizes in an orthorombic (pseudo-tetragonal) space group P212121 and bromotetrakis(3,4-dimethylpyridine)cobalt(II) bromide (2) in a monoclinic space group C2/c. Cell parameters are obtained from Guinier-Haegg powder data: a=7.6742(8), b=7.6742(8), c=28.114(6) A and Z-4 for 1. and a=14.817(4), b=13.290(5),c=14.871(4) A, beta=90.55(3) and Z=4 for 2. In 1 the cobalt(II) ion is tetrahedrally coordinated with an approximate C2v symmetry, which is apparent from the infrared spectrum. In 2 the cobalt(II) ion has a rarely observed five coordination with square pyramidal geometry. The consequent spectral symmetry is C2v. The thermal decomposition pattern of samples is simple: an one-step process for 1 (DTG maximum at 335C) and a three-step process for 2, where one, one and two ligand moles are successively released (DTG maxima at 130, 193 and 360C).

The Rh(I)-catalyzed direct arylation of azines has been developed. Quinolines and 2-substituted pyridines couple with aryl bromides to efficiently afford ortho-arylated azine products using the commercially available and air-stable catalyst [RhCl(CO)2]2. Electron-deficient and electron-rich aromatic bromides couple in good yields, and hydroxyl, chloro, fluoro, trifluoromethyl, ether, and ketone functionalities are compatible with the reaction conditions. Aroyl chlorides also serve as effective azine coupling partners to give ortho-arylation products via a decarbonylation pathway.

The direction of the magnetic moment of the substrate defines different adsorption rates for different enantiomers, and the direction of the electric field, perpendicular to the surface, defines different adsorption rates depending on the direction of the dipole moment of the adsorbed molecules.

The enantiomeric excess is a key parameter for chemical and pharmaceutical industries for its ability to determine the activity and therapeutic action of chiral compounds. The determination of the enantiomeric excess using nuclear magnetic resonance is generally based on the formation of diastereomeric complexes. Herein we report novel chiral oxo-bridged calix[2]arene[2]triazine derivatives, which were synthesized from (1S,2R)-(-)-1-amino-2-indanol or (1S,2R)-(+)-2-amino-1,2-diphenylethanol. The structures of these compounds were established by various spectroscopic methods. Their enantiomeric recognition abilities towards the enantiomers of alpha-racemic carboxylic acids were examined by using 1H NMR spectroscopy. The DeltaDeltadelta values of alpha-H signals were appropriate to give a good baseline resolution for most of the tested analytes, which ranged from 0.005 to 0.053 ppm. The alpha-hydroxy acids, especially those containing aromatic group such as mandelic acid, alpha-methoxyphenylacetic acid, showed a bigger DeltaDeltadelta value in comparison to the other carboxylic acids.
