(Chemical Equation Presented) Step by step: Highly selective cross dehydrogenase arylation of acetanilides was developed to construct biaryls under mild condition. With this method, different aryl C-H bonds were activated in sequential reactions to construct functionalized carbazoles (see scheme), which are present as key structural units in various biological molecules and organic optical materials.

Javelin-, hockey stick-, and boomerang-shaped liquid crystals. Structural variations on p-quinquephenyl

, p. 8845 - 8860 (2007/10/03)
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.

Boronic acids act as transition-state analogues for certain peptidases. the inhibitory effect of 2-, 3- and 4-biphenylylboronic acids (2a, 2b and 2c) on the hydrolytic activity of α-chymotrypsin has been investigated.These inhibitors were employed to monitor the binding event occuring in the active site by a fluorescence method.It was shown that the decrease in the fluorescence intensity, which is induced by the formation of a covalent bond with the boronic acid moiety, is well correlated with the inhibitory effect estimated by kinetic measurements.The inhibitory effect appeared in the order 2a i = 1.6 x 10-6 mol dm-3).Intetrestingly, the inhibitory effect was further intensified by added saccharides.In particular, the combined system of 2b and D-glucose strongly inhibited the enzyme reaction, the inhibitory effect (Ki = 1.1 x 10-7 mol dm-3) being stronger than that of a specific inhibitor, chymostatin (Ki = 4.8 x 10-7 mol dm-3).Hence, saccharides act as a 'co-inhibitor' in the boronic acid inhibition system.This is a novel and efficient inhibition system for α-chymotrypsin (and probably more generally for other peptidases).
