Criton, Thomas;Vilona, Debora;Jacob, Guy;Medebielle, Maurice;Dumont, Elise;Joucla, Lionel;Lacote, Emmanuel research published 《 Synthesis and Properties of Higher Nuclearity Polyazanes》, the research content is summarized as follows. Polyazanes (i.e., higher nuclearity homologues of hydrazines) with increasing numbers of bound nitrogen atoms (from 3 to 5), including the first pentazane ever described, were prepared by the addition of lower-order polyazanes to diazo reagents. It was shown that the polynitrogen chains adopt a helical conformation. DFT modeling shows that the arrangement persists in solution Although the polyazanes are all reducing agents, they become less so as the number of nitrogens increases.

Oxyquinoliziniporphyrins I (R = Et, n-Bu), novel carbaporphyrinoids that incorporate quinolizone units, were synthesized.

Several phenanthrolinic analogs of quinolones I [R¹ = OH, NH₂, OEt, NHNH₂, NHPh; R² = H, Cl, Br, NO₂; R³ = H, Me, Et; R⁴ = H, NO₂] were synthesized and their antibacterial activity tested against Mycobacterium tuberculosis, other mycobacterial species and bacteria from other genera. Some of them show high activity (of the range observed for rifampicin) against M. tuberculosis replicating in vitro and in vivo (infected macrophages) conditions. These derivatives showed the same activity with all or several M. tuberculosis complex bacterial mutants resistant to fluoroquinolones (FQ). This opened the way to the construction of new drugs for the treatment of FQ resistant bacterial infections, including tuberculosis. Several compounds showed also activity against Staphylococcus aureus and probably other species. These compounds did not showed major toxicity.

Clothier, Glenn K. K.;Guimaraes, Thiago R.;Moad, Graeme;Zetterlund, Per B. research published 《 Expanding the Scope of RAFT Multiblock Copolymer Synthesis Using the Nanoreactor Concept: The Critical Importance of Initiator Hydrophobicity》, the research content is summarized as follows. Precise multiblock copolymer synthesis coupled with self-assembly offers morphol. control on length scales ranging from a few nanometers to micrometer scale, providing enormous opportunities for future development of advanced materials and applications. The scope of multiblock copolymer synthesis via RAFT polymerization has recently been expanded by application of the nanoreactor concept for emulsion polymerization This enabled use of slow propagating monomers, such as styrenes and methacrylates, in multiblock synthesis. However, severe limitations attributed to the high polymer glass transition temperature (T_g) of some polymers have hitherto remained. The use of monomers that give such high T_g polymer effectively prevented penetration of aqueous phase-generated radicals into the polymer particles wherein the RAFT functionality is located. We here demonstrate that these constraints can be relieved by judicious choice of the radical initiator. Multiblock homopolymers were synthesized by seeded RAFT emulsion polymerization using initiators that differ substantially in hydrophobicity. Ten sequential chain extensions using tert-Bu methacrylate (T_g of PtBMA = 118°C) with targeted block DP = 100 were conducted at 80°C for each initiator. Markedly narrower mol. weight distributions were obtained when more hydrophobic initiators were used. The same polymerizations targeting low T_g polymer (PnBMA; T_g = 20°C) resulted in only minor differences in control when the different initiators were used, supporting our hypothesis on the role of radical penetration. The present results are anticipated to significantly expand the scope of RAFT polymerization in aqueous emulsion by allowing access to a wider range of low dispersity multiblock copolymers.

Cioc, Razvan C.;Smak, Tom J.;Crockatt, Marc;van der Waal, Jan C.;Bruijnincx, Pieter C. A. research published 《 Furoic acid and derivatives as atypical dienes in Diels-Alder reactions》, the research content is summarized as follows. The furan Diels-Alder (DA) cycloaddition reaction has become an important tool in green chem., being central to the sustainable synthesis of many chem. building blocks. The restriction to electron-rich furans is a significant limitation of the scope of suitable dienes, in particular hampering the use of the furans most readily obtained from biomass, furfurals and their oxidized variants, furoic acids. Herein, it is shown that despite their electron-withdrawing substituents, 2-furoic acids and derivatives (esters, amides) are in fact reactive dienes in Diels-Alder couplings with maleimide dienophiles. The reactions benefit from a substantial rate-enhancement when water is used as solvent, and from activation of the 2-furoic acids by conversion to the corresponding carboxylate salts. This approach enables Diels-Alder reactions to be performed under very mild conditions, even with highly unreactive dienes such as 2,5-furandicarboxylic acid. The obtained DA adducts of furoic acids are shown to be versatile synthons in the conversion to various saturated and aromatic carbocyclic products.
