Congratulations to Johnathan Matlock who was awarded a prize for his poster at the recent CSCB symposium: “Recent Advances in Synthesis and Chemical Biology XIII“. The symposium, which was held in UCD, featured lectures from Profs Steve Buchwald (MIT), Guy Lloyd-Jones (Edinburgh), Dirk Trauner (Munich), Joost Reek (Amsterdam) and Rebecca Goss (St Andrews). ‘Johno’ presented his poster on the synthesis and applications of vinylsulfonium salts, focusing on the synthesis of heterocyclic compounds. This success follows on from publications in J Org Chem and Chem Eur J over the course of his PhD (jointly supervised by Eoghan and Prof Varinder Aggarwal (Bristol)). Johnathan will submit his PhD thesis very soon.

New paper in J Org Chem
Our latest paper has been published in the Journal of Organic Chemistry. The paper describes a way to make α-substituted vinylsulfonium salts and their application to the synthesis of pyrrolidines fused to either epoxides or cyclopropanes. These heterocycles should be useful building blocks for medicinal chemists. The paper arose from an ongoing collaboration with Prof Varinder Aggarwal at the University of Bristol, and researchers at GlaxoSmithKline. Congratulations to lead author Johnathan Matlock in particular, this is the second publication arising from his ongoing PhD research (supervised by Eoghan and Varinder).
The paper is published online in the Journal of Organic Chemistry and can be accessed at the following link (with a subscription):

The research was funded by EPSRC (Bristol Chemical Synthesis CDT), GSK, SFI and Marie-Curie COFUND.
Johnathan Matlock wins a poster prize
Congratulations to Johnathan Matlock who won 1st Prize for Best Poster Presentation in the Organic & Biological Section of the 3rd Royal Society of Chemistry Younger Members Symposium. Johnathan presented his latest research on the synthesis of heterocycles using vinylsulfonium salts at the meeting in Birmingham on June 24th. Johnathan is jointly supervised by Eoghan and Prof Varinder Aggarwal and is a student in the Bristol Chemical Synthesis CDT. His PhD is sponsored by GSK and the EPSRC.
Paper published in Chemistry a European Journal
Our latest paper has just appeared online in Chemistry – A European Journal. The paper describes the use of vinylsulfonium salts to synthesise cyclopropane-fused heterocycles from readily available starting materials with excellent levels of diastereoselectivity. These interesting structures should be of particular interest to medicinal chemists. This paper arises from an ongoing collaboration with the Aggarwal group at the University of Bristol, UK. We thank EPSRC, GSK and SFI for funding.

Paper published in Helv. Chim. Acta
Our latest paper was published online in Helvetica Chimica Acta in a special edition in honour of Prof Dieter Seebach’s 75th birthday. The paper describes the use of a new chiral vinylsulfonium salt for the synthesis of epoxide and aziridine-fused heterocycles. The method was applied to a synthesis of the core of the mitomycin class of antibiotics. This work was carried out in collaboration with Prof Varinder Aggarwal, Sven Fritz, Zulfiquar Ali and Dr Matt Unthank at the University of Bristol.

Paper published online in Organic Letters
Our latest paper was published online in Organic Lettters as an ‘as soon as possible’ article. The paper describes the use of trifluoromethyl-substituted vinylsulfonium salts for the synthesis of saturated heterocycles containing the CF3 group. The epoxide-fused heterocycles are expected to be of interest to medicinal chemists in particular. This work was carried out in collaboration with Prof Varinder Aggarwal, Sven Fritz and Tom West at the University of Bristol. We thank EPSRC and SFI for funding.
