Rapid determination of enantiomeric excess

Synthesising compounds asymmetrically has obvious advantages – scientists don’t have to go through the laborious and wasteful process of separating then discarding the ‘wrong’ enantiomer. Huge libraries of compounds can be tested for their ability to catalyse a reaction of interest but determining the enantiomeric excess (ee) of the products is a bottleneck in the process.

So researchers have been developing high-throughput ee screening methods that can analyse samples as quickly as they are generated, ideally at a rate of a thousand or more per day.

Eric Anslyn and colleagues explore this topic in their Chem Soc Rev critical review, specifically focusing on optical methods. Download the review to find out about the advantages and drawbacks of a variety of techniques.

Twice as nice

The eagle-eyed among you may have noticed a subtle change to the Chem Soc Rev homepage. Can you spot it?

Well, Chem Soc Rev will be doubly good next year as we’ll be moving to 24 issues.

So if you are subscribed to our e-alert, you’ll get two notifications per month about the latest topical reviews we’ve published. And if you read the print issues, you’ll find it a bit easier on the biceps when lifting them – there shouldn’t be any with more than 1000 pages like issue 5 this year.

If you have any suggestions for the journal, such as review topics or themed issue ideas, we’d love to hear them. Please contact us or leave your comments below.

Glycopeptide antibiotics – recent advances in synthesis

More than 50 years on from the discovery of vancomycin, there is still huge demand for novel glycopeptides antibiotics. Vancomycin’s clinical use was initially limited due to its side effects but the rise in the number of methicillin-resistant bacteria forced it back to the forefront of research. Now vancomycin-resistant bacteria are on the increase and so scientists have been trying to make new glycopeptides antibiotics in a variety of ways.

Graphical abstract: Recent advances in the synthesis of new glycopeptide antibioticsThis fascinating topic is covered by Polly-Anna Ashford and Sean Bew, at the University of East Anglia, in their recent Chem Soc Rev tutorial review. Download it today to find out more about this intriguing class of compounds.

Converting carbon dioxide into useful chemicals

Recently I blogged about the importance of green chemistry in process research and development. But making the things we need in a greener way is only one step in our journey to a more sustainable lifestyle. Dealing with the waste we produce is also crucial.

Graphical abstract: Recent advances in catalytic hydrogenation of carbon dioxideIn the latest issue of Chem Soc Rev (7), Jinlong Gong and colleagues explore how we can deal with carbon dioxide (CO2) waste. As most of us know, CO2 produced by burning fossil fuels is a major contributor to global warming. Unsurprisingly, working out how to reduce its level in the atmosphere is a major area of research. There are three possible strategies – reducing the amount we produce (i.e. burn less fossil fuel); capture and store the CO2 we do produce; or use it.

CO2 is an attractive building block for making organic chemicals and materials, says Gong, but currently its use is limited to a few industrial processes. It is thermodynamically stable so high energy substances or electroreductive processes are used to transform it into other chemicals.

The group discuss the steps scientists have taken to improve the hydrogenation of CO2, which can produce useful chemicals such as methanol, ethers, and hydrocarbons. They cover catalyst design, reactor optimisation and reaction mechanisms as well as the challenges and opportunities for future research in the field.

Beating cancer using nanogold

Graphical abstract: Beating cancer in multiple=

Gold – people lust after it, buy things with it and decorate objects and themselves with it. But what many people don’t know is that gold can also help to cure cancer.

Gold nanoparticles have a combination of properties, different from bulk gold, which enable them to act as potent, selective and multifunctional anti-cancer agents. They can be used in photothermal cancer therapy, drug delivery, gene therapy and cell cycle regulation. 

In their Chem Soc Rev tutorial review, Mostafa El-Sayed and colleagues from Georgia Institute of Technology, Atlanta, USA, discuss these anti-cancer applications as well as strategies for the synthesis/design of biomedical gold nanoparticle conjugates.

Wine – delicious and scientific

Last night I bumped into one of my Chem Soc Rev colleagues, Bryan (Publishing Editor), at a charity wine tasting event – not literally: I didn’t have that much wine.

It was a really enjoyable evening. Not only was there nice wine and nibbles, there were also quite a lot of science-y facts.

 

Some things I learned:

  • Wine has legs but they don’t necessarily indicate high alcohol content.
  • Wine changes colour as it ages due to oxidation. Both red and white wine eventually turn the colour of onion skin, according to the wine expert.
  • Terroir is the ‘sense of place’ the wine has, influenced by the geography, geology and climate of the place it was produced.
  • Wines with higher sugar and acidity content keep for longer.

If you like a drop yourself and fancy learning more about the science behind the wine, check out these articles:

The importance of green chemistry in process research and development

Graphical abstract: The importance of Green Chemistry in Process Research and DevelopmentConcern for our planet and its well being is forcing chemists to think about greener, more sustainable processes to make the things we need and want, such as new technologies, fuels and drugs.

In the pharmaceutical industry, solvent selection plays a huge role in determining the ‘greenness’ of a process. In his Chem Soc Rev tutorial review, Peter Dunn (Pfizer Worldwide Research and Development) gives a basic guide to green chemistry, with information on solvents and solvent selection, basic environmental metrics collection and three industrial case histories.

Chem Soc Rev Lecture Award – winner announced

Stephen LeoneIt gives me great pleasure to announce, on behalf of the Chem Soc Rev Editorial Board, that the winner of the 2011 Chem Soc Rev Lecture Award is Professor Stephen Leone, Professor of Chemistry and Physics at the University of California, Berkeley, and Director of the Chemical Dynamics Beamline and Chemical Sciences Division at Lawrence Berkeley National Laboratory.

The Chem Soc Rev Lecture Award is given to honour a scientist who has made a significant contribution to their field over the course of their career. The Editorial Board praised Professor Leone’s varied research career, which has been characterised by the development of a great number of novel methods for probing dynamical processes. These have included infrared emission techniques for ion-molecule chemical dynamics, laser single photon ionisation of gaseous species during epitaxial growth and ultrafast soft X-ray generation and probing.

Professor Leone’s award will be presented at a conference later in the year. Details will follow in due course.
