CORE Newsletter, Issue 2 - October 2019

Welcome to the CORE newsletter!
The biannual CORE newsletter has the goal to keep you updated on all CORE related activities. If you have any news, ideas or comments to share feel free to contact us!

Welcome to the second newsletter from the CORE Network
The CORE Network has been in full operation for 3 years now and we are happy to report that many results on the deracemization of chiral compounds have been achieved, several of which can be found in this newsletter. The ‘core’ of any scientific project is always formed by publications in the scientific literature, but an Innovative Training Network (ITN) such as CORE has in addition a strong emphasis on training of the early-stage researchers (ESRs). This aspect in particular has been very successful. A group of young researchers with many different nationalities have by now (nearly) completed their visits to both partner groups and participating industrial partners. This has given the ESRs a unique perspective on the way science is done in different locations, together with exposure to different cultures. The many joint schools, meetings and workshops have led to genuine bonding between the members, and have generated a positive and friendly atmosphere within the group. This means that the CORE network will result, next to the scientific tool box, in 15 ESRs who are well-equipped to continue their careers in an academic or industrial environment.
We wish you happy reading of the many network activities as well as the exiting science that you will find in this newsletter.
Joop ter Horst (CORE Network Coordinator) and Elias Vlieg (Core Network Dissemination Committee Chair).

Success Stories: CORE Project, European Commission

The European Commission recently published a success story about the CORE ITN:

New processes for safer medicines

The EU-funded CORE project is helping to develop safer, more effective medicines by improving the processes pharmaceutical companies use to separate mirror-image pharmaceutical molecules, which will boost the industry's efficiency and competitiveness.  To read the full article, click here:


Poster Prize

ESR Ryusei Oketani (University of Rouen) was awarded Chemistry of Materials Best Poster Prize at 24th International Conference on the Chemistry of the Organic Solid State (ICCOSS XXIV), 16-21 June 2019, New York University. The poster was entitled 'Phase diagram study and chiral resolution of axially chiral naphthamide derivative'.


Journal Cover Profile

ESR Ryusei Oketani (University of Rouen) was invited to submit for the cover of this issue of Chemistry: A European Journal. The image depicts pyramid‐like tetrahedron of the quaternary phase diagram showing where symmetry breaking can take place. Read the full text of the article at 
10.1002/chem.201903338. : “Deracemization in a complex quaternary system with a second‐order asymmetric transformation using phase diagram studies” R.

CORE Research Work Packages

WP3: Towards Continuous (ESRs 1 to 4)
With three published papers and more in the making, Work Package 3 is proceeding well towards the goal of continuous resolution of chiral conglomerate-forming compounds and of racemic compound-forming systems at the eutectic. Process simulations and experimental work based on either preferential crystallization and temperature cycling have been the main routes investigated. Clopidogrel, one of the model compounds of interest, has also been used to face these challenges.

WP4: Hybrid Resolution (ESRs 5 to 9)
The development of new racemization routes as well as the optimization of process parameters are the main topics covered by Work Package 4. Racemization represents sometimes a bottleneck for Viedma ripening, temperature cycling and second order asymmetric transformation (SOAT), which are the processes studied in this WP. As of now, eight papers have been published and more will soon be submitted. Praziquantel (another model compound suggested to the CORE network) together with Clopidogrel are currently being used by some of the ESRs of this WP. 

WP5: Enabling Resolution (ESRs 10 to 15)
ESRs of Work Package 5 are currently working on different tasks covering i) co-crystal predictions and analysis for new conglomerate-forming systems; ii) conglomerate detection using second harmonic generation (SHG); iii) resolution of racemic systems through their stable/metastable conglomerate and of conglomerate co-crystals by means of preferential crystallization processes and iv) development of Process Analytical Tools (PAT) for online monitoring of resolution processes. Three publications by this WP are now available and more have been submitted/ will soon be submitted. 



CORE Events

The final CORE Workshop took place from 8-11 October 2019 in Erlangen, Germany hosted by Beneficiary Partner Friedrich - Alexander  University  Erlangen - Nürnberg, Germany (FAU).  This event ended with a mini open symposium on Friday 11 October, with keynote speakers:

Prof. Malte Kaspereit, Institute of Separation Science & Technology (Friedrich-Alexander University, Erlangen-Nuremberg, Germany)
Advanced processes based on chromatography and allied techniques toproduce single enantiomers [abstract]

Professor Gerard Coquerel, CORE Principal Investigator(University of Rouen, France)
Chiral Discrimination in the solid state [abstract]

Prof. Jan-E Bäckvall, Department of Organic Chemistry (Stockholm University, Sweden)
Deracemization of Alcohols and Amines via Chemoenzymatic Dynamic Kinetic Resolution    [abstract]


Summer Schools




During the CORE project, the 15 ESRs spend part of their research training with network partners undertaking visits/ secondments. The goal of each visit/ secondment is to prepare joint scientific papers. For all ESRs, visits/ secondments are planned at the secondary supervisor institute, at an academic partner as well as at an industrial partner. In addition to their knowledge skills development, the secondments provide interdisciplinary training and intersectoral awareness will be facilitated. The duration of each secondment is planned together with the host supervisors.
