Meet one of our brilliant scientists who makes Science for a Safer World possible: Shireen Ahmed talks a bit about her career in science, nucleic acid chemistry products and more. #ScienceforaSaferWorld

Kathleen Lonsdale. Born: 1903 in Newbridge (Ireland) Died: 1971 London (England) Main achievements: She proved, in 1929, that the benzene ring is flat by using X-ray diffraction methods. #laedysophietienequimica #laedysophie #quimica #chemistry #benceno #benzene #benzenerings #anillosdebenceno #xraydiffractionmethod

🥳I am so excited to share with you that my first project as PhD student in the Masson Group was just published in JACS!! 🥳 In deeply, a warm thank you to my supervisors Géraldine Masson and Luc Neuville for their motivation and their guidance, as well as Dr. Marine Lombard for your collaboration on this work. Many thanks to everyone else involved and of course to my dear friends of the ICSN for your unfailing support during this first year. ❤️ ⚗️If you are interested in organocatalysis, asymmetric synthesis or cycloaddition reactions, or just because you are curious about what «  Enantioselective and Regiodivergent Synthesis of Dihydro-1,2-oxazines from Triene-Carbamates via Chiral Phosphoric Acid-Catalysis » might mean, just click here ;) https://lnkd.in/ekecRyU9

Happy Thanksgiving! I am also glad to share that my second paper at Rutgers University–New Brunswick is officially published today @Chem. Commun. "Redox-active ligand promoted electrophile addition at cobalt" https://lnkd.in/em9sC3nk We demonstrate a redox-active ligand acts as a two-electron reservoir and promotes Co–CF3/F bond formation through ligand-to-substrate electron transfer which can be rationalized with their redox potentials. It is the application in organic reactions of our previously published work @Inorg. Chem. "Two-Electron Redox Tuning of Cyclopentadienyl Cobalt Complexes Enabled by the Phenylenediamide Ligand" https://lnkd.in/eMjQiZKs

Check out our recent publication on the "beneficial" degradation of photocatalyst and its impact on the halogen-atom-transfer reaction, published in Angewandte Chemie as an accepted article!

A little late on posting, but my 1st publication in Synthesis is out! https://lnkd.in/g8Z5XTJF A palladium-catalyzed decarboxylative dearomatization of a heterocyclic benzyl ester enabled access to an uncommon reaction intermediate that can rearomatize with simple amine bases. The dearomatized intermediate was also taken for further functionalization reactions (the IEDDA [4+2] cycloaddition was my personal favorite). Thanks to my fellow authors and to Synthesis for the invitation to the special issue on the C-H functionalization of heterocycles!

I am pleased to share with you my recent publication in Angewandte Chemie - "Rhodium-Catalyzed Asymmetric Macrocyclization towards Crown Ethers Using Hydroamination of Bis(allenes)". Chiral crown ethers (CEs) exhibit strong asymmetric induction in phase transfer catalysis, supramolecular catalysis and molecular recognition processes. In this study, a practical catalytic asymmetric macrocyclization method is described for the gram-scale synthesis of a class of chiral CEs using Rh-catalyzed hydroamination of bis(allenes) with diamines. Using this approach, a wide range of chiral CEs with ring sizes ranging from 12 to 36 were successfully prepared with high enantioselectivity. This project was accomplished in the Breit Group. I appreciate the nice discussions we had during this project. https://lnkd.in/evF5jdcJ
