Copper-Catalyzed Substitution of alpha-Triflyloxy Nitriles and Esters with Silicon Nucleophiles under Inversion of the Configuration

A copper-catalyzed nucleophilic displacement of alpha-triflyloxy nitriles and esters with silicon nucleophiles allows for the stereospecific generation of highly enantioenriched alpha-silylated carboxyl compounds. The enantioselective synthesis of alpha-silylated nitriles is unprecedented. The catalytic system exhibits good functional group tolerance. The stereochemical course of the substitution is shown to proceed with inversion of the configuration. The new reaction is an addition to the still limited number of methods for catalytic C(sp3)-Si cross-coupling.

Spatial variations in the occurrence of potentially genotoxic disinfection by-products in drinking water distribution systems in China

We investigated the occurrence of disinfection by-products (DBPs) with genotoxic potential in plant effluent and distribution water samples from four drinking water treatment plants in two Chinese cities using comprehensive two-dimensional gas chromatography?quadrupole mass spectrometry. We tested the samples for 37 DBPs with genotoxic potential, which we had previously identified and prioritized in water under controlled laboratory conditions. Thirty of these DBPs were found in the water samples at detection frequencies of between 10% and 100%, and at concentrations between 3.90 and 1.77 ¡Á 103 ng/L. Of the DBPs detected, the concentrations of 1,1,1-trichloropropan-2-one were highest, and ranged from 299 to 1.77 ¡Á 103 ng/L with an average of 796 ng/L. The concentrations of 6-chloro-2-N-propan-2-yl-1,3,5-triazine-2,4-diamine and 2,6-ditert-butylcyclohexa-2,5-diene-1,4-dione were also much higher, and ranged from 107 to 721 ng/L, and from 152 to 504 ng/L, respectively. Concentrations of 1,1,1-trichloropropan-2-one, 2-chloro-1-phenylethanone, 2,2-dichloro-1-phenylethanone and 6-chloro-2-N-propan-2-yl-1,3,5-triazine-2,4-diamine were highest at or near the treatment plants and decreased with increasing distance from the plants. Patterns in the concentrations of benzaldehyde, 2-phenylpropan-2-ol, and 1-methylnaphthalene differed between plants. The levels of DBPs such as 4-ethylbenzaldehyde, (E)-non-2-enal, and 1-phenylethanone were relatively constant within the distribution systems, even at the furthest sampling points (20 km < d < 30 km). A risk assessment showed that there was no risk to human health. It is, however, important to note that, because of limited availability of toxicity data, only five DBPs were evaluated in this study. The risks to health associated with exposure to the target potentially genotoxic DBPs should not be ignored because of their prolonged existence in drinking water. The potentially genotoxic DBPs behaved differently within the distribution systems. There were no human health risks from the five DBPs assessed.

Inhibitors of human nitric oxide synthase isoforms with the carbamidine moiety as a common structural element

Identification of potent and selective inhibitors of inducible nitric oxide synthase (NOS) is of great interest because of their therapeutic potential for treatment of diseases mediated by excess production of nitric oxide. We present here a comparison of potency and selectivity for amino acid and nonamino acid based compounds as inhibitors of human inducible, human endothelial constitutive and human neuronal constitutive NOS isoforms. In addition, a novel series of substituted amidines has been identified as NOS inhibitors. 2-Methylthioacetamidine and 2-thienylarbamidine were the most potent of the series examined with IC50 values of 3.9 and 2.9 muM for human neuronal constitutive NOS. Cyclopropylcarbamidine and 2-thienylcarbamidine were the most potent inhibitors for human inducible NOS with IC50 values of 5.2 and 6.5 muM, respectively. These substituted amidines represent a new class of NOS inhibitors and provide a foundation for potential therapeutic agents.

Synthesis and Study of Molecular Assemblies Formed by 4,6-O-(2-Phenylethylidene)-Functionalized d -Glucosamine Derivatives

Low-molecular-weight gelators are interesting small molecules with potential applications as advanced materials. Carbohydrate-based small molecular gelators are especially useful because they are derived from renewable resources and are more likely to be biocompatible and biodegradable. Various 4,6-benzylidene acetal protected alpha-methyl 2-d-glucosamine derivatives have been found to be effective low-molecular-weight gelators. To understand the influence of the 4,6-benzylidene acetal functional group toward molecular self-assembly and to obtain effective molecular gelators, we synthesized and analyzed a new series of d-glucosamine derivatives in which the phenyl group of the acetal is replaced by a benzyl group. The homologation of the acetal protection from aromatic to aliphatic functional groups allows us to probe the effect of increasing structural flexibility on molecular self-assembly and gelation. In this study, nine representative amides and nine urea analogs were synthesized, and their gelation properties were analyzed in a series of organic solvents and aqueous solutions. The resulting amide and urea derivatives are versatile organogelators forming gels in toluene, ethanol, isopropanol, ethylene glycol, and aqueous mixtures of organic solvents. More interestingly, the amide analogs are also effective gelators for pump oil and engine oil. NMR spectroscopy at variable temperatures was used to analyze the molecular assemblies and intermolecular forces. The selected gelators with several drug and dye molecules in DMSO and water were studied for their effectiveness of encapsulation and release of these agents.
