Identify the reagents 2- April 2021

A recent paper by a team from Merck describe the synthesis of a soluble guanylate cyclase (cGC) stimulator of interest for the treatment of hypertension. Can you identify reagents or intermediates B, F and the target compound H? Answers and a reference will be posted in May, along with another problem. Enjoy!

Identify the reagents 1: answers

Last month I posted a scheme from a paper by Jonathan H. George et al at the University of Adelaide describing a biomimetic total synthesis of the Rhododendron meroterpenoids rubiginosins A and G and asked if you could identify reagents or intermediates B, D, E and H. Below are the answers! You can read more here

Conference Brochure – 2021

Conferences for Industrial Process Chemists and Engineers are continuing ONLINE. As the Covid virus continues to cause travel restrictions, we have persisted to host our popular meetings virtually. We still invite top quality speakers and provide thought provoking programmes aimed at an industrial audience and have developed several new tools to enable us to offer

Process Chemistry Jobs

Did you know that we have a ‘Job Area’ on our website? If you have a vacancy and are looking for a process chemist or chemical engineer, why not post your position on our website? We have 1,000’s of visitors looking at our site for process chemistry training and events, so thought this is an

Biocatalysis: Enzymatic Synthesis for Industrial Applications

Biocatalysis is becoming ever more popular and prevalent in the synthesis of fine chemicals, agrochemicals and pharmaceuticals and is c becoming much more widely used in industrial chemical processes generally, so this review is very timely. The review includes sections on the synthesis of “Alcohols”, “Amines”, “Carbonyls, Carboxylic acids and Derivatives”, “Glycosylation”, “Complex Molecules” and

Pyrylium salts- kryptonite for the Sandmeyer reaction?

I often stumble across interesting chemistry when I peruse my twitter feed. It’s not only rich in new chemistry highlights and ASAP links to journal articles but also chemists sharing their own experiences with both new and existing methodology- good, bad, and sometimes with pictures!- a dimension missing from just reading peer-reviewed journal articles and,

Could this be a case for Mulder and Scully? – Aryl ether synthesis under mild conditions

As with all things in life, necessity is the mother of invention. Synthetic chemistry, as an enabling science, will always rise to the challenge and meet the increasing demand for simpler and more efficient methods to construct fundamentally important structures and functional groups, particularly if these units are conserved privileged pharmacophores imparting biological activity to

The I’s have it- 1,2-diamination of unactivated olefins using catalytic iodine

Any new synthetic methodology, as well as advancing the state of the art, should also consider a few other key criteria, one of which is to build complexity from common feedstock materials- ideally using cheap and environmentally friendly reagents and raw materials. Unactivated (or unsubstituted) olefins, used largely by the polymer industry, represent a rich

A radical approach to C-H chlorination

My first experiences of radical chlorination where something of a baptism of fire. Generation of chlorine radicals from chlorine gas under intense UV irradiation in a custom-made photochemical flow reactor was as scary as it sounds to a very young, yet to be trained chemistry technician starting out in his carrier in the chemical industry.
