A Nifty Thrifty Route to Photoredox Catalysis

One of the most significant technological advancements in synthetic organic chemistry in recent years is the use of photoredox catalysis to generate synthetically useful radical intermediates and promote novel reactivity. It has the potential to enable exploration of chemical space that remains difficult to access using traditional synthetic methodology and too improve the efficiency of

The Phantom Menace

When I started my PhD one of my then colleges spent months trying to make something that was sitting on a shelf in the chemical store room less than ten feet from their bench. Could there really be anything more frustrating? Well yes there could. Imagine finding a new catalytic process or synthetic transformation only

New Award for Young Chemists

Boron sees the light- A visible light induced organocatalytic borylation of aryl chlorides

Aryl boronates are among the most widely used synthetic intermediates in the pharmaceutical and agrochemical industries, both in R&D and commercial manufacture.1 Historically these key building blocks have been made using transition metal (Pd, Cu, Ni) catalysed cross coupling reactions between an appropriate aryl halide (usually bromide,  iodide or activated chlorides) and an alkoyboron species.2 Efforts to

Reagent of the Month- 2,2,2-Trichloro-1,1-dimethyl chloroformate

Netarsudil- a ROCK kinase inhibitor marketed by Aerie pharmaceuticals as RhopressaTM– was recently approved by the FDA for ocular hypertension.1 An asymmetric synthesis is challenging due to the aryl group lowering the pKa of the α-hydrogen, rendering it very susceptible to racemization both during synthesis of the amino acid and subsequently amide coupling to an unreactive, poorly

5 Minutes with Dr Boris Gorin, Eurofins Alphora

Dr John Studley, Scientific Director at Scientific Update recently spoke to Dr Boris Gorin, Eurofins Alphora, Toronto, Canada ahead of his presentation at the 2019 ‘Organic Process Research & Development’ Conference in Toronto, Canada. Boris will talk about “Eribulin Mesylate, a Journey from Synthetic Route Discovery to Scale-Up Manufacture”. John Studley (JS): Can you tell us a bit

Scientific Update to Sponsor Award at Chemical Industries Association (CIA) Awards Celebration

Chemical Industries Association (CIA) Awards Celebration Thursday 13th June 2019 St George’s Hall, Liverpool Scientific Update is proud to sponsor the ‘Young Ambassador’ Award at the Chemical Industries Association (CIA) Awards Celebration in Liverpool, 13th June. This award will be presented to an outstanding young person demonstrating communication skills and leadership associated with the chemical

2 more cocrystal APIs on the market

Following a communication from a chemist at Merck / MSD I can now tell you about 2 more cocrystal APIs on the market – Lexapro (escitalopram oxalate) and Steglatro (ertugliflozin pyroglutamic acid cocrystal.  Lexapro is actually a cocrystal of the salt escitalopram oxalate with oxalic acid, similar in some ways to the Praziquantel intermediate naproxen

“Inconvenient Truths about Solid Form Landscapes”

The keynote speaker at our recent ‘Polymorphism and Crystallisation’ Conference in Boston was Dr Susan M. Reutzel-Edens from Eli Lilly, whose name will very familiar to anyone working in the solid form / crystallisation and she gave what one delegate described as “the best talk I have ever heard”. Now I can’t entirely agree with

3 cocrystal API’s now on the market

There are now 3 cocrystal API’s (Entresto, Suglat, and Depakote) on the market meaning that this area is no longer just an academic curiosity. Entresto is a cocrystal formed from the sodium salts of sacubitril and valsartan, but I do not know whether that is affected by the current furore over N-nitrosoamine impurities found in
