Scientific Update is delighted to announce the appointment of Dr John Studley, formerly Head of Process Chemistry for Vertex Pharmaceuticals, UK. John will join the team at Scientific Update in August 2018 as Scientific Director bringing over 20 years’ experience in drug discovery, process chemistry and scale up, having previously worked for Rhone-Poulenc, Oxford Asymmetry and Vertex…

Process Chemistry Articles

Preparative chromatography is a versatile purification technique used in various industrial sectors including petrochemistry, sugar production, pharmaceutical and fine chemistry, to name only a few. While this technology is often considered complex, expensive and sometimes not scaleable, industrial success stories prove the opposite. In our recent webinar, Dr. Pfister from Ypso-Facto presented a reliable approach…

A patent just issued last month to Sachem, one of the most veteran manufacturers of high purity quaternary ammonium phase-transfer catalysts, that describes how to inhibit color formation of quat hydroxides in non-aqueous solvents (glycols). Sachem has been a leader in the commercial supply of quat hydroxides, especially those used in the manufacture of semiconductors.…

A short review article, also from the group of Igor Larrosa at Manchester, on the use of aromatic carboxylic acids as coupling partners in biaryl synthesis, appeared earlier in European Journal of Organic Chemistry (2017, 3517-3527). It is suggested in the micro-review that benzoic acid derivatives are atom-economic alternatives to traditional cross  coupling partners, and…

The brominative decarboxylation  reaction was demonstrated over a hundred and fifty years ago by Borodin (the famous composer, whose day job was as Professor of Organic Chemistry) and later developed by Hunsdiecker, whose name the reaction now bears. From an industrial viewpoint the transformation would be useful but the need to have a stoichiometric silver…

Process Chemistry Articles

Phase-transfer catalyst or PTC is a catalyst that facilitates the migration of a reactant from one phase into another phase where reaction occurs. Phase-transfer catalysis is a special form of heterogeneous catalysis. Ionic reactants are often soluble in an aqueous phase but insoluble in an organic phase in the absence of the phase-transfer catalyst. The catalyst functions like a detergent for solubilizing…

Published in Green Chemistry in 2018 C. Oliver Kappe is our tutor on our Flow Chemistry course and this abstract was published in Green Chemistry showing a collaboration with Lonza in making an API in flow. Abstract: Fluoroform (CHF3) can be considered as an ideal reagent for difluoromethylation reactions. However, due to the low reactivity…

If you had suggested 10 years ago that it would be a good idea to try and develop some of the reactions that you can now carry out using photoredox catalysis, you would probably have been labelled as deluded, if you were not locked away for your own safety.  But photoredox catalysis has come a…

Conference reviews

We had a fantastic turn out for our #OPRDUS18 Conference in Clearwater, Florida last month. It was great to see our speakers, exhibitors and attendees and the feedback we received was excellent. Thank you for coming along! Our Technical Director Dr Will Watson opened the conference and we invited Dr Paul Murray and Dr André de…
