  Substituted oxazole benzenesulfonamides as potent human β3 adrenergic receptor agonists

  摘要：

  As a part of our investigation into the development of orally bioavailable beta(3) adrenergic receptor agonists, we have identified a series of substituted oxazole derivatives that are potent beta(3) agonists with excellent selectivity against other beta receptors. Several of these compounds showed excellent oral bioavailability in dogs. One example, cyclopentylethyloxazole 5f is a potent beta(3) agonist (EC50 = 14 nM, 84% activation) with 340-fold and 160-fold selectivity over beta(1) and beta(2) receptors, respectively, and has 38% oral bioavailability in dogs.

• Direct Oxidative Cross-Coupling of Toluene Derivatives and<i>N</i>-Acyl-2-aminoacetophenones

  The direct oxidative cross‐coupling between N‐acyl‐2‐aminoacetophenones and toluene derivatives was developed with a new C–C bond being formed under metal‐free and environmentally friendly conditions with excellent atom economy. A possible reaction pathway for the formation of the products is also discussed in this paper.

  Aryl alkyl thioethers are an underutilized class of alkyl radical precursors that are demonstrated to outperform their well-established sulfone analogues under electroreductive conditions. Single electron transfer results in C−S bond cleavage and alkyl radicals that may react in C(sp3)−C(sp3) bond forming events or undergo radical-polar crossover, followed by protonation or carboxylation to furnish

• Javelin-, Hockey Stick-, and Boomerang-Shaped Liquid Crystals. Structural Variations on <i>p</i>-Quinquephenyl

  The ramifications of changing molecular geometry in a series of all-aromatic liquid crystals derived from p-quinquephenyl are reported. Substituting heterocyclic rings such as thiophene, oxadiazole, oxazole, or 1,3-phenylene into the p-quinquephenylene core affects molecular shape changes via the substituent's exocyclic bond angle. In general, we found that introducing nonlinearity into molecules depresses the melting transition temperature. The symmetric (boomerang-shaped) molecules, 2,5-bisbiphenyl-4-yl-1,3,4-oxadiazole, 2,5-bisbiphenyl-4-yl-oxazole, and 1,3-bisbiphenyl-4-yl-benzene, melt into isotropic phases showing small monotropic mesophases. By contrast, the asymmetric (hockey stick-shaped) mesogens, 2-terphenyl-4-yl-5-phenyl thiophene and 2-terphenyl-4-yl-5-phenyl-1,3,4-oxadiazole, exhibit more stable enantiotropic liquid crystalline phases. The hockey stick-shaped mesogens exhibit a smectic phase as well as a nematic phase. High-temperature X-ray determination of the smectic layer spacing gives an unambiguous picture of interdigitated, bilayerlike supramolecular architecture in the smectic phase. There are associated changes in the mesogen's electrostatic profile when a heterocycle is introduced into the quinquiphenylene framework (e.g., conjugation is perturbed). Our findings suggest that steric packing considerations dominate the phase preferences (nematic versus smectic phases), However, electronic considerations (conjugation) appear to control the range of mesomorphism in this new family of nonlinear liquid crystals.
