A method for the bromination of alkoxy-substituted benzenes and naphthalenes was developed by using the residual oxygen in the reaction tube as the oxidant, and [Bmim]NO3 (1-butyl-3-methylimidazolium nitrate) ionic liquid as both the catalyst and the solvent. No other reagent apart from the ionic liquid and molecular bromine was used in the reactions, and basically all the bromine atoms in the bromine source were transferred to the bromination products, showing that the presented protocol is highly atom economic and practical.

A simple, rapid and highly regioselective green protocol has been developed for the halogenation of aromatic systems with N-halosuccinimides using room temperature ionic liquids (ILs) as novel and recyclable reaction media to produce the corresponding halogenated aromatic compounds in high to quantitative yields. N-Halosuccinimides show enhanced reactivity in ionic liquids thereby reducing the reaction times dramatically and improving the yields substantially.

Gangjee et al. recently reported a novel series of 2-amino-4-methyl-5- phenylethyl substituted-7-benzyl-pyrrolo[2,3-d]pyrimidines, some of which exhibited two digit nanomolar antitumor and antimitotic activity and were not subject to P-glycoprotein (Pgp) or multidrug resistance protein 1 (MRP1) mediated tumor resistance (unlike the Vinca alkaloids and taxanes). Some of these compounds, in addition to their antitumor activity, had the ability to reverse the Pgp-mediated resistance to clinically used antimitotic agents. This report consists of an attempt to optimize the various activities of the parent compounds by synthetic variations of the phenyl ring of the 5-phenylethyl side chain. The target compounds were synthesized via a nine-step synthesis involving a Sonogashira reaction. The substituted phenylacetylenes as coupling partners were in turn synthesized from unactivated aryl bromides or iodides. The target compounds exhibited moderate cytotoxicity against MCF-7 tumor cells. However, most of these compounds showed improved cytotoxicity against the resistant NCI/ADR and MCF-7/VP. This study afforded an analog which reversed both Pgp-mediated as well as MRP1-mediated resistance to clinically used antimitotic agents, along with its own antimitotic mediated antitumor activity. In addition, in the NCI-60 cell line panel one of the compounds inhibited the growth of MDA-MD-435 breast cancer cell line at submicromolar concentration.

Open versus Closed Polyaromatic Nanocavity: Enhanced Host Abilities toward Large Dyes and Pigments

Host functions of polyaromatic nanocavities were revealed by using an M2L4 molecular cage and capsule. On the basis of the previously reported M2L4 capsule with a closed polyaromatic cavity, a new M2L4 cage (as a mixture of the isomers) was prepared by the quantitative assembly of two metal ions and four desymmetrized bispyridine ligands with a single polyaromatic panel. The obtained, open nanocavity of the cage exhibited enhanced binding abilities toward large dyes and pigments in water. For example, two molecules of coumarin dyes were bound in the nanocavity and showed strong whitish emission (up to PhiF=34 %). Furthermore, metallopigments, the sizes of which are larger than the inner cavities of the cage and capsule, were bound only in the open polyaromatic nanocavity of the cage to give water-soluble 1:1 host?guest complexes.

A versatile and efficient halogen-promoted highly regio- and stereoselective Friedel – Crafts (F-C) alkylation with alkenes has been developed with use of easily available and inexpensive NBS or I2 as the efficient halogen sources. Lewis acids, in particular metal triflates, are found to be effective catalysts for this halogen-promoted F-C alkylation. Among these, Sm(OTf)3 was the best catalyst. Electron-rich arenes smoothly underwent F-C alkylation with a variety of alkenes including alpha,beta-unsaturated carbonyl compounds.
