Direct monohydroxylation of benzene and substituted benzenes was successfully performed by anodic oxidation to form the corresponding phenol derivatives in good yields. The anodic oxidation was generally carried out in a mixed solvent of trifluoroacetic acid and dichloromethane containing triethylamine using a divided cell equipped with a platinum plate as the anode, a carbon rod as the cathode. Benzene derivatives having electron withdrawing groups were suitable for the present electrochemical oxidation. It was clarified that aryltrifluoroacetates were formed as the initial products from the reaction of the radical cations, generated by one electron transfer from the substrates, with trifluoroacetic acid, followed by hydrolysis during work-up to give the corresponding phenols.

A phosphine-catalyzed cascade (2+3)/(2+4) cyclization reaction of γ-vinyl allenoates with aldimine esters has been developed to provide a series of chromeno[4,3-b]pyrrole derivatives that contain three contiguous stereogenic centers. The method gives a good yield, excellent chemoselectivity and diastereoselectivity under mild conditions.

Fullerene-Filled Liquid-Crystal Stars: A Supramolecular Click Mechanism for the Generation of Tailored Donor–Acceptor Assemblies

Two shape-persistent star mesogens with oligo(phenylene ethenylene) arms and a phthalocyanine core—one providing free space (2) and one sterically encumbered by four fullerenes attached through spacers (3)—have been successfully synthesized. In contrast to the smaller discotic derivative 1, mesogen 2 forms a columnar liquid crystal (LC), which can only be partially aligned without π-stacking, while 3 is not an LC. Exceptionally, the 1:1 mixture of 2 and 3 forms an alignable columnar LC with strong π-stacking and quadruply helically organized fullerenes by an unprecedented click process that is similar to a ball detent mechanism. The C60 units also interconnect different columns. This is driven by nanosegregation and space-filling of the voids with fullerenes. Photophysical studies confirm the presence of a light-collecting system that generates charge-separated states in solution and in the solid state, which makes such highly organized materials attractive for the study of future photovoltaic devices.

NMDA receptors are tetrameric complexes composed of GluN1 and GluN2A-D subunits that mediate a slow Ca2+-permeable component of excitatory synaptic transmission. NMDA receptors have been implicated in a wide range of neurological diseases and thus represent an important therapeutic target. We herein describe a novel series of pyrrolidinones that selectively potentiate only NMDA receptors that contain the GluN2C subunit. The most active analogues tested were over 100-fold selective for recombinant GluN2C-containing receptors over GluN2A/B/D-containing NMDA receptors as well as AMPA and kainate receptors. This series represents the first class of allosteric potentiators that are selective for diheteromeric GluN2C-containing NMDA receptors.
