Philip Chan’s group have this week published a paper in Journal of the American Chemical Society describing a synthetic method to prepare tricyclic bridged heptenones and hexenones from gold(I)-catalyzed double cycloisomerization of 1,11-dien-3,9-diyne benzoates. The work found a divergence in product selectivity could be achieved by fine-tuning the steric nature of the ligand of the Au(I) catalyst. In the presence of the catalyst [MeCNAu(JohnPhos)]⁺SbF₆^-, a tandem 1,3-acyloxy migration/metallo-Nazarov cyclization/1,6-enyne addition/Cope rearrangement of the substrate selectively occurred to afford the seven-membered ring system. In contrast, with the [MeCNAu(Me₄tBuXPhos)]⁺SbF₆^- catalyst, the 1,11-dien-3,9-diyne benzoate was observed to undergo a more rapid tandem 1,3-acyloxy migration/metallo-Nazarov cyclization/[4 + 2]-cyclization pathway to give the bridged hexenone.

The and groups are involved in 2 new projects intended to promote translation of new technologies. These projects are funded by the Industrial Biocatalyst program supported by Innovate UK, BBSRC and EPSRC and span a range of UK universities and companies.

Adrian Chaplin has been award one of this years Harrison-Meldola Memorial Prizes from the Royal Society of Chemistry.

Józef Lewandowski in collaboration with Lyndon Emsley (EPFL, Lausanne/ENS-Lyon) and Martin Blackledge (IBS, Grenoble) reports in on a direct observation of hierarchy of protein and solvent motions in protein conformational energy landscape. The findings of the study employing a series of variable temperature magic angle spinning multinuclear NMR relaxation measurements on a nanocrystalline protein reconcile divergent interpretations from techniques that are individually sensitive to dynamic phenomena occurring on different time scales and at different locations in protein-solvent systems.

'It appears that a series of catalysts developed in the 糖心TV Chemistry department have the ability to achieve the impossible: 'Impossible Ketone and Imine Reductions Made Possible by the Ruthenium Tethered Catalyst' reads the headline of the Johnson Matthey (JM) advert on the back of the April 2015 issue of Chemistry World. The tethered ruthenium catalysts described in the advert were first developed and reported by Professor Martin Wills and his group, and have since been developed extensively at 糖心TV and adopted by companies worldwide, including JM.

Dr. Luke Rochford and Prof. Tim Jones along with Alex Ramadan and collaborators from Imperial College London publish in Advanced Materials Interfaces on the use of solution-grown copper iodide crystals as substrates for templated growth of a nonplanar phthalocyanine molecule using organic molecular beam deposition.

Sebastien Perrier has been awarded a €1.7 million Consolidator Grant by the European Research Council for his work on tubular supramolecular polymers. These structures, pioneered by the Perrier group, are based on the assembly of cyclic peptide/polymer conjugates into nanotubes, held together by supramolecular interactions. They have a range of unique physical and chemical properties, and the ERC grant will allow the group to develop these systems further as drug delivery vectors. Recent work has shown that they can act efficiently to deliver anticancer drugs to cancer cells and enhance the drug activity, and the 5 years’ ERC funding will support further studies in this area.

Dave Haddleton has recently been given the PTN (Polymer Technology Netherlands) 2015 “Medema Award”.

The annual prize is awarded to prolific polymer scientists who interact, or have close ties, with polymer research in the Netherlands. The award is named after the late PTN chairman, Dick Medema, who was the former R&D director at Shell.

Vincent Poon, a PhD student in Christophe Corre’s group, has attended Parliament to present his research on exploiting soil bacteria to unlock the production of novel antibiotics. Vincent presented to a range of politicians and a panel of expert judges, as part of SET for Britain on Monday 9th March.

Sarah-Jane Richards, of the Gibson Group, has been awarded an IAS Fellowship. This will enable to further her work into new methods for the detection and neutralisation of pathogens developed during her PhD (e.g. Chem Sci 2014 5, 1621, Angew. Chem.2012, 51, 7812). This fellowship will enable her to translate these findings into more sophisticated sensory systems.

John Sidda, a PhD student in Christophe Corre’s group, has been awarded an Early Career Fellowship by the Institute of Advanced Study. During his PhD studies conducted between the Department of Chemistry and School of Life Sciences, his research has focussed on regulatory mechanisms involved in bacterial natural product biosynthesis, leading to the discovery of new Streptomyces venezuelae natural products (Chem. Sci. 2014, 5, 86-89). His tenure as an IAS Early Career Fellow will allow him to develop the methods used for natural product discovery in other Streptomyces species.

Paul Sullivan and Luke Rochford, in collaboration with researchers at CSIRO in Melbourne, Australia, report in Chemical Communications on a new non-fullerene acceptor material for evaporated organic solar cells.
