Malononitrile dimer as a precursor reactant has been extensively applied in the diversity-oriented synthesis of various heterocyclic motifs, bis-heterocyclic compounds, fused heterocycle derivatives, bicyclic bridged heterocyclic scaffolds, and highly substituted carbocyclic compounds. These remarkable products were synthesized via various types of reactions, such as cycloaddition, cyclocondensation, cascade/domino/tandem reactions along with multi-component reactions. In addition, the flexibility and high reactivity of malononitrile dimer as a multi-functional reagent and its potential to the preparation of novel beneficial scaffolds as well as biologically active molecules signify it as a suitable building block in total synthesis, medicinal chemistry, and dyes. In the present review, the advances in the chemistry of malononitrile dimer as a potent reagent in organic synthesis have been reported in the past to now.

Stacking interactions can play an integral role in the strength and selectivity of protein-drug binding and are of particular interest given the ubiquity and variety of heterocyclic fragments in drugs. In addition to traditional stacking interactions between aromatic rings, stacking interactions involving heterocyclic drug fragments and protein salt bridges have also been observed. These “salt-bridge stacking interactions” can be quite strong but are not well understood. We studied stacked dimers of the acetate¡¤¡¤¡¤guanidinium ion pair with a diverse set of 63 heterocycles using robust ab initio methods. The computed interaction energies span more than 10 kcal mol-1, indicating the sensitivity of these salt-bridge stacking interactions to heterocycle features. Trends in both the strength and preferred geometry of these interactions can be understood through analyses of the electrostatic potentials and electric fields above the heterocycles. We have developed new heterocycle descriptors that quantify these effects and used them to create robust predictors of the strength of salt-bridge stacking interactions both in the gas phase and a protein-like dielectric environment. These predictive tools, combined with a set of qualitative guidelines, should facilitate the choice of heterocycles that maximize salt-bridge stacking interactions in drug binding sites.

The first 4-position-selective C-H perfluoroalkylation and perfluoroarylation of six-membered heteroaromatic compounds were achieved using nucleophilic perfluoroalkylation and perfluoroarylation reagents. The regioselectivity was controlled by electrophilically activating the heteroaromatic rings, while sterically hindering the 2-position, with a sterically bulky borane Lewis acid. The reaction proceeded in good yield, even in gram scale, and by a sequential reaction without isolating the intermediates. This reaction could be applied to late-stage trifluoromethylation of a bioactive compound.

The light-driven artificial enzymes were constructed to realize unnatural reactions concerning bio-significant molecules. In this manuscript, the guanosine triphosphate (GTP)-selective oxidation is reported using the network polymers composed of polyhedral oligomeric silsesquioxane (POSS). We synthesized the water-soluble POSS network polymer containing the naphthyridine ligands to capture GTP inside the networks and the ruthenium complexes to oxidize the captured GTP under light irradiation. Initially, the binding affinities of the guanosine nucleosides to the naphthyridine ligand inside the POSS network polymer were evaluated from the emission quenching experiments. Accordingly, it was observed that the naphthyridine ligand can form the stable complex only with GTP (Ka = 5.5 ¡Á 106 M-1). These results indicate that only GTP can be captured by the network polymer. Next, the photo-catalytic activity of the ruthenium complex-modified POSS network polymer was investigated. Finally, it was revealed that the network polymer can decompose GTP efficiently under light irradiation. This is the first example, to the best of our knowledge, to offer not only the GTP-selective host polymers but also the light-driven artificial enzyme for GTP oxidation. the Partner Organisations 2014.
