Grateful for a successful defense, and I’m extremely excited to share (super late announcement 😅) that I’ll be joining the Pfizer - La Jolla team as a Senior Scientist

[Raymond Twumasi 🇬🇭 @_ChemistRay]

I’m looking forward to all the great talks and interactions at #ACSSpring2025. I’ll be presenting a poster on Wednesday evening. Swing by!😁

Are you #team_abstraction or #team_substitution to break C-Cl bonds? Check out work by Samir, Imma, and Blaise in @angew_chem on an electrocatalytic system that can switch between these mechanisms to functionalize unactivated chloroalkanes. https://t.co/Ky5DAK1VxY

@BagPhos Congrats!!

[Raymond Twumasi 🇬🇭 @_ChemistRay]

Impressive work

Ever wanted a cross-metathesis … but with carbonyls?

Check out Prof @LuminZhang123’s last discovery before starting his own lab at SIOC … in @NatureChemistry

It’s like a reverse ozonolysis!

Super paper in @OPRD_ACS by my #PfizerChemistry colleagues in Process chem developing a hydrogen free debenzylation
By enabling a Ni-catalyzed cross coupling with MeMgBr to spin off ethyl benzene! Great use of an inverse reaction strategy

Last week, we held our annual Paper of the Year meeting, during which we celebrated the great chemistry published in 2022. This year’s winner was the @nagiblab’s Carbene Reactivity from Alkyl and Aryl Aldehydes https://t.co/SzQAoblYpU

[Scott Bagley @BagPhos]

A wonderful paper out now in @OPRD_ACS from the #PfizerChemistry team detailing the work that went into Lufotrelvir which was under development alongside Nirmatrelvir/Paxlovid - just amazing work done on compressed timelines during lockdowns
